Now you can enjoy smoother Metal Slug 2 without overclocking. Actually with OC it might even run as fast as X, but my motherboard is just a standard one.

Enjoy.

Cool. Interesting to know that SNK built Metal Slug X from the ground up. I was always of the opinion that X > 2, but after playing 2 quite a lot it does feel a little better (and with this, hopefully better still). Can't wait to try this.

That looks like a pretty significant improvement! Fantastic job!
Now I'm just wondering how well this would run in 2 player mode. I love Metal Slug 2 but 2 player in that just goes way overboard with the slowdown.

Yeah it's not night and day, but it feels better to play, sadly that's as far as it can really go without disabling graphical features or rewriting lots of code. Trap15 had a look into this for me after I .. encouraged him to spend some time on it for me, but there were no other obvious big wins to be had. I guess that's why SNK wrote a new engine in the first place.

It would still be terrible in 2p I'm afraid. The train level is still pretty rough too, apparently the code which tracks the train movement is somehow really slow.

Yeah, I figured that would be the case... Still, even with the slowdown MS2 is still a blast to play with 1 player, and this fix would help a lot, especially with some of the more notorious choking points like the bridge on the final mission.

Very nice work.

I wonder if this is something the unibios could catch via a cheat?? I may have a look if I find some free time to see if that's doable if your ok with that.

Nice work!! can a M27C160 be used with the fixed code in the lower half and the original code in the upper half (or viceversa) and solder a switch to the highest address line to switch between version? also, I guess some jumpers gotta be moved in the board, right?

Regards.

Yes a 27C160 will work as a replacement for the 27C800. Just lift pin 1 (A18) and switch that between 5v (via 4K7 resistor) and ground on the other end of the switch. If the cart is using a 1Mb chip already there's no need to change the jumpers.

It's also cleaner to use a 74HCT161 or something to switch between ROMs using reset. I did that on my Magician Lord.

I remember we where talking about doing the switch with reset about a year ago. Cool to see at least someone did it :)
Are you able to test and see if the /RST is pulsed when you switch games on a multislot?

Not really. If that was something someone wanted to do, they'd have much better luck just hacking X to change things to be like 2. Trying to replace an entire engine's just not worth it or really feasible.

Nice, so it did have something to do with updating, just not game logic. From the comparison vids it's like night and day. Is it true that in the PS2 MS Anthology version of MS2 that SNK just super over clocked the game to try and fix the slowdown?

trap15
03-29-2015, 08:13 PM
Well, I'd really not call it even updating. It's just the lock code is terrible. The game logic is really slow though, as system11's post mentions. It's really really slow. They didn't put much work into optimizing the game.

I'm assuming the anthology versions just overclock the emulated machine, yeah. I doubt they went through the effort to optimize it. I've not looked, but I don't think it's even worth checking; it's almost a guarantee.

No problem, If you change you mind in the future please let me know. Don't expect the multicart makers to be so understanding.

Can you confirm you will be keeping the game ID at 0x0941 in case you make future changes so I can tie that ID in the unibios to the standard MS2 cheats? Ohh and for high score saving also.

I have looked at this a little more now in relation to unibios feature support only and I would suggest you do not change the game ID from 0241 to 0941. Although I can see your logic and understand the reason for changing it there is one factor you may not be aware of as a consequence of this change.

An updated unibios supporting this game ID is required if you want to be able to correctly play this version on an AES in Arcade mode. All Metal Slug games have this same issue (apart from MS1) and the unibios works around it but it expects an ID of 241 for Metal Slug 2 and not 941.

I can easily add 941 to a future unibios version to fix this issue (and add highscore saving and cheats) but it may be easier to simply keep the ID at 241 so people will not require a new unibios.

May I ask what the reasons are? Having Unibios support would bring this to so many more people, especially if it works with multi-carts. It would also save all of those physical copies of MS2 that have to be operated on for the fix.

This is excellent.

System11, you should reconsider Raz on the Unibios thing.
That would avoid tons of MS2 to be modified.
I understand you have your concerns, but at least think about it ;)

Plus ( altough it's just a small minority ) , AES carts would benefit from that too as nobody would want to "ruin" their copy.

Ah now this is a valid issue, I'll have a word with trap about it. Until that number was changed (under mame at least) it was refusing to pick up the cart name change unless the number changed too.

Yes that would happen and normal because the backupRAM only saves the name the first time its stored, if there is already a MS2 store in backupRAM it won't update. If you clear the backupRAM from test mode however it should then pickup the new name. That new name will stay even if a original MS2 is added back.

It gets a little complex but its not a good idea to compare in emulation backupRAM related situations because emulation does not treat it in the same way as real hardware. MAME saves a separate backupRAM for every game. Real hardware only saves backupRAM for a possible 8 games and I would say that it is unlikely someone will use your patch and the original ms2 together in normal situations on real hardware unless its simply to compare.

Personally If I had done the patch I would have left the game ID and game strings the same and instead maybe have something drawn on the title page to show its your turbo version.

Be aware that it may be difficult to close the cart if you put a socket in the board. You may have to trim some of the plastic from the shell.

You can install the turbo patch into sockets ep1 and ep2 if you remove the jumper that connects p1 /oe to ground and tie it to +5v.

So, by using this method it is also possible to switch between the turbo/regular chips, by switching...OE I think?

I don't know about the ps2 version but the wii is like that. I messed with the wii version and it had the ms2 roms in it unaltered.

@System11,

I have another suggestion for you. If you are still set on trying to find a way to keep the ID at 941 another option would be to include patches to patch out the game protection. This is related to writes and checks to address 0xD00100 (used for backupRAM protection). Doing that would solve the issue I mention above as the unibios would not need to work around that protection any longer with your mod.

mjsaville
03-31-2015, 07:16 AM
I for one have MS2 on a couple of Multi-Carts, and would love the increased frame rate, etc.

However if the patch cannot be tied to the UNIBios then a lot of people will not justify purchasing the MS2 cart + EPROM programmer just for the slight performance increase. I personally would be gutted too.

The other side of the coin is - I'm off to buy up all the MS2 Carts on ebay :glee:, as a price increase must surely be around the corner when people rush to buy them to modify. This I think would be sad though....

In short, I hope "System11" reconsiders so it can be tied to the UNIBios, the UNIBios has come so far over the years it is the logical place for storing fixes and patches like this.

I had a bunch of 27C4096 so I went with those.

Remove J10 and move to J1 if needed. Seems like most boards will have J1 populated all ready.

Use a pull up resistor on the P1 /OE from the bottom of J8,J9 or J10 to the top of JB5 or JB6

Split 941-P1. First 512KB on EP1, Second 512KB on EP2. Burn onto two 27C4002/27C4096 eproms 120ns or faster.

Forgot I sold my MS MVS set last year, luckily I found an MS2 mask rom boot. Pulled the p1 and put in the new data and played a game. I would say that the fix made a huge improvement over the original speed. I'd say it's an increase of 60-75%, feels great.

Me and EG put one together and put a couple hours of play on it. We first credit fed it 2player. It seemed to be doing well until level 3. Pretty much any time after that if we both used HMG and anything more than a couple sprites where on screen it ground to down to a crawl. Overall 2player is just as painful as it ever was.

Now one player is a different story. Almost all the places where the original slowed down the Turbo roms fixed it completely. A good example is the airboats, the turbo roms blast right through them.
It doesn't fix it all, like the final bridge, but the overall pacing an feel for the game is now no longer a grind and is a real joy to play.

Had a long think about the NBH and so on, and I'm afraid I'm happy with the release as it is. It does what it set out to do in the way I wanted.

So, if anyone out there with an AES and a MVS cart wants to use it, you'll need to fix the number yourself before you burn the chip. Get a hex editor, change address 109h from 09 to 02. Job done.

Just converted a mint cart which is my permanent keeper now, having the chance to switch my socketed one back to the normal version showed me the difference is actually greater on MVS than it is in MAME, just wow.

I could have tried to add it as a cheat into the unibios (if possible) I would have of course given a mention in the readme (link to your url etc) and could have added a custom cheat line message if it fits. That would have got around this situation.

That aside the IPS patcher is the way to go. Does it leave the NGH to the default?

I used the patcher today, instead of the ROM you distributed before. Worked perfectly.

I did the socket method; since my Slug 2 had a non-original label, I went ahead and moved my boards into a Chinese shell which didn't require any dremel work for the boards to fit back in.

Just played it for about an hour and am loving it! Thanks for putting this out there for us.

You will need to clear out the solder from the two EP locations and can leave the original P1 on the board. As posted before, you can switch back & forth between the original & turbo version.

Right, I'm not trying to belittle the work. I'm a software developer myself and I know that sometimes even the simplest things can turn out to be the hardest to implement/fix. I read through the technical rundown trap15 posted (http://daifukkat.su/blog/archives/2015/03/30/its_turbo_time/) and it seems to be an update of only 2 functions. More than likely I suspect the time to diagnose and find the problem was far longer than actually fixing it and testing the code! Pretty crazy to think that this area would've been overlooked with a game that had this much slowdown. Certainly not where I would've looked first.

I'm in Europe and have stock of 27C4096's and an Eprom burner. Can do for the cost of chips + shipping.
You will need to clear out the solder from the two EP locations and can leave the original P1 on the board. As posted before, you can switch back & forth between the original & turbo version.

As awesome as I think this patch is, I just can't see modifying my cart for it. I'll have to wait for a Neo Geo multi cart some day before I try it out on hardware.

What's so wrong with replacing one ROM? It significantly improves the game, it's like that hitbox fix for SS3. Besides, properly done, no harm is inflicted to the original chip in the swap. Or you can do what bustedstr8 did and took advantage of the EP sockets.

ill wait till you decide not to post it back up again. there was no point in taking it down. nor the bs restrictions which no one will follow. i wasn't planning on making any carts besides my own. i just find the arrogance of rom hackers appalling. its not your game. if you did not want it out in the wild don't release it. dont sell carts your self and dont whine when others pay little attention to some grand scheme or readme.txt

if you did it to share cool put it back up and let even those who dont have eprom flashers and means to also have.

Right now, I'm just trying to get that person to apologise.

I fucking hate people who make money off freely donated fixed and code. Nothing makes me angrier in fact. I have no issue with the peeople who were making chips or fitting this at low cost, you're right not everyone has the equipment. There's a line of acceptability though, and aside from your statement above there was nothing bad going on here. I didn't even profit from it myself, I sold *one* cart, my tatty old one I'd used for testing, for the same price an unmodified cart would be, and including the original chip. That simply left me 'slightly less out of pocket'.

Can't stand the self entitled nature of some people. Selling this undermines the good faith in which it was released for free. I kind of expected to see them floating around eventually, if someone gets their cart altered and then decides to sell it later - yep, obviously going to happen. Eventually I imagine several will be changing hands floating around. 1 fucking month though? That ebay item was made to sell, it's already more expensive than a plain slug 2 and not even a Buy It Now.

Haven't been this angry for some time.

I rarely respond like this.

Fuck you, you entitled piece of shit. In fact I mentioned your name in IRC and someone who wasn't even following the conversation came out with 'lol werejag, king of freeloading' so yeah, looks like you already have a poor reputation anyway.

Whole intent was to release this totally for free, EULA and switching to a patcher from the initial 'just release the image' method was to do with protecting me in case SNK ever took a look at it and decided I was trying to make money from their IP, and also to try to discourage people leeching off the community by selling modded carts while not causing trouble for people genuinely helping the community by making or fitting chips at cost. If you don't understand that you're more stupid than you sound.

snk was never going to care.

the eula was non binding as all eulas are. its really not up to you to decide what price something can be charged. again i also plan not to sell copies.

Yeah I appreciate what you're saying too. If Metal Slug 2 MVS is still a $30 cart, that's what I'd pass it on as.

Unfortunately, part of the problem here is the Neo-Geo scene doesn't have that many games or options to profit and exploit. Diggerman is a perfect example of this. It's a crummy game, but it's still a game. Slug 2 Turbo will likely end up in a similar position as the SS3 hitbox patch or the Slug X P ROM decryption.

@System11, some people just don't get it but at the same time I can't say its not unexpected to see it happening, not unexpected at all. You are going to have to accept that its going to show up in a new multicart if more types are make in the future.

Its a reason I asked you if I could try and add the patch to the unibios (I would have given you full credit, link to webpage etc, could mention something on the cheat line if it fits). I then accepted your decision when the answer was no.

The offer still stands if you change your mind and it could be done. This would also be a rare occasion where I could add the patch into the released and free version at the same time so there could be no claim I was trying to make money from it. It would also save the modding of good MS2 or the conversion of other games and people trying to make money from it. If this could be done it would simply mean people buying these carts are wasting money if they can use a free unibios to do the same thing. Your credit for it would also not be lost.

Yeah, i'm breaking my lurking streak here and i absolutely agree. You don't want people profiting off your work you gave away? Then you should maximize the supply, exactly the opposite of what you were doing. Make it available for UniBIOS, advertise and distribute it properly. It only helps you in the end: If i didn't know neo-geo.com and its community, i'd be really tempted to buy that cart off eBay right this moment, but if i knew i could use it via UniBIOS then i would just spend the 30 euros for an EPROM instead of feeding the scummy resellers.

Indeed, I just modified a spare MS2 cart I had and tried it. Huge improvement, the game has almost no slowdown, feels very nice. Also, in case anybody is asking, it does work with MVS converters, I tried it on an AES with Magic key converter. Played perfectly, however the UniBIOS won't save to memory card the high scores you make with this cart. I guess it's because it identifies itself with a different code (941 vs 241 on original MS2, hopefully Raz can add this variant of the game to next UniBIOS version so it will save the high scores).

Regards.

Yep, I thought of doing it, but didn't. After playing the game, I found out I am not that good at MS2 when played faster, so I think it's fair having separated scores for both variants of the game.

Can anyone please tell me if when running the turbo patch on real hardware you see a sprite glitch during the title page drawing in attract mode. What you are looking for is the words 'Metal Slug' flashing once quickly as the large '2' falls into the screen.

This is something I am seeing in emulation when I try the patch and I wondered if that's an emulation related thing only or happened on real hardware also.

I just tried a cart with the turbo patch on an Omega and I did not notice anything.

Maybe not, Raz. I kept watching the attract mode, and it seems some times there is a glitch like what you describe. It does not happen always, and I could not find a pattern quickly, but it did happen after I posted before. If you need more details or tests, I'll help you.

Ohh that's a real shame, I was hoping I was wrong even though its a really minor issue. The fact no one has brought it up kind of shows how minor a problem it is, given it can happen during gameplay also. Are you able to confirm for me that it never happens in the normal version of the game?

Replaced a P1 this weekend. The patch is awesome! Some slowdown in certain hectic stages but a solid 80% improvement overall. It's like a new game. Works on both my CMVS and AES w/blue MVS converter.

Yes it happens occasionally, strangely it happens much more often in emulation than hardware. I've only ever seen it happen on the title screen and once in the character select with the shutters, never seen it happening in-game.

There is also another glitch - you can see it most obviously in stage 1 with the 3 towers - look above the score line and you'll see some lines flashing near the tops of the towers. Interestingly this even happens on the normal game in emulation or hardware, but it's more frequent in turbo.

Also in response of one of the posts somewhere up the page, the programming was actually done by trap15, I hired him :) My programming skills stop at C.

Not even then, not even close. X is the better game, people that prefer 2 over X simply prefer it 'cause it's more doable for them. Oh it's ok, I understand you're lured by the friendly slowdown, it's ok, one day you'll come to terms with being a slow poke.

HeavyMachineGun hooked me up with a copy of the patched MS2 for an extremely generous $30. I played it all the way through in 2-player mode and actually enjoyed it for the first time. It was pretty much broken before and was embarrassing to the MVS as a system. With the slowdown reduction patch it feels like a real game now, and not like some kind of bad port from another system. The videos can't do justice to how big the improvement makes to the actual feel of the game.

I was thinking exactly the same, desoldering the chip takes more time because it should be done very carefully to not damage the traces or vias, the soldering is way easier and is done way faster IMO. Also, if OP only needs the programming of the chip, Fox1 has the required service.

Because of how the patch works that is not really possible. I have looked at it (with permission from system11) but the cause of the slowdown and the patch are not as explained in either of the write ups out there from my short time looking at it. This is why there are minor problems with it in some areas of the game, that said it still makes the game more playable than the original version.

You mean there is going to be a new unibios soon? :D Looks like I might want to buy that one! Can you try to get some nice codes for the NGDevTeam games, like perhaps speedups, power ups, extra lives, extra continues for the Last Hope and Fast Striker carts that do not have credit feed options, (the 1.0 big boards)? stuff like that?

I am also hoping that one day you can find a way that will make the Jukebox work with the NGDevTeam games so I can just sit back and listen to the music in those games, since they are by far some of the best sounding game music on the Neo-Geo, and since NGDevTeam refuses to add option menus to their games, and refuse to add in sound test menus, and general stuff that made the AES games AES games, perhaps you can find a way to add these features using the unibios on them? :) I mean, if we can just start to get some support for the NGDevTeam games on the UniBios I would happily buy myself one, as I have been wanting to support the UniBios for a long time now. I really do!

BTW, what new stuff will be included in this new 3.3 UniBios? I am getting excited! :)

I could just listen to the OST on CD since I own all the CD's of the games, but, that is not the point. I want to actually listen to the Cart music like I do with all my AES games. Somehow it is just more fun to do it that way, and listen to the tunes directly from the chips. I am old fashioned, and I love sound test menus on games, and music test menus.

The unibios cannot fully support the NGDEV games because they are written in a way that does not allow the ingame menu to be brought up. I think you can get access to the jukebox though on the MVS at least. Probably can on the AES also but your blind because there will be no font.

Yes, the screen is garbled on the AES, but, the problem is not really that, the problem is that they stream the music in a way that the Jukebox only can see and play around 4 songs, and then after that, the unibios repeats those same 4 songs as you go up higher in numbers. The NGDevTeam told me that in order for the UniBios to play the music back properly, that you would need to write the code for that player to read "higher banks" that the other songs are located at. So, I figured if you knew this info, you could find a way to access the other songs as well. I mean if anyone can do it, it would be you since your the master of the Neo-Geo when it comes to coming the UniBios, and you made the NeoJukebox as well, so if the NeoJukebox can play some of the songs just fine on NGDevTeam game carts on the AES, then you should be able to find a way to access the higher banks that stream those songs. Perhaps create a special player that can access ALL the NeoGeo music from any game, no matter what it is. That would really be amazing!

Also, I would LOVE it if you could ever be able to write the NeoJukebox to do what the NeoGeoStation does for it's Jukebox player? I REALLY love using that on the PS3, because it is VERY much like the one on Ninja Spirit on the TurboGrafx 16, where you can literally see every single track that the console has to offer, and when the musical instruments are played on each of those tracks, you can see the little colored bars bouncing up and down, or back and forth, to indicate which channels are being used, and how high the sound is getting for each channel. This is something I have been dying to see on the Neo-Geo for ages, and I would be willing to pay some good money JUST to see that get added to the UniBios!

So, can you please look into these things on the UniBios and see if these can be added to future versions of the Uni? That would be SO COOL, Raz!

Razoola
11-16-2015, 06:04 AM
The unibios can already play banks... the 0x07 is the bank number. Just scroll through until its 0x08 for example and that would send the code for the next bank. The other suggestion is not possible on the NeoGeo. you know the sound is controlled by a totally separate cpu and there is no access to it directly to get that kind of information

Well, to be honest, most people prefer MS2 over MSX for many reasons. The Background colors in MSX were horrible compared to MS2. Little things were taken out of MS2 to make X run a bit faster, like the little dust that your feet make in the first stage when running across the sand, (or were just overlooked). Also, many people don't like the reorganization of the bosses, things like that. I personally thought MSX was nice just for the speed up difference, but, other than the game running faster it was not as beautiful as MS2 was. It certainly was not worth them making it an all new game to buy for $299.99 only one year later, and it basically being nearly the same exact game. It was almost as blatant a rip off as Neo-Geo Cup 98.

I do believe that the general consensus is MS2>MSX. That, and MSX is not on the Neo CD either. :P

I applied Raz's patch to MS2 CD and it runs perfectly in emulation, but on both of my CD-Zs it crashes after selecting a character with the error:
"Device I/O Error
Code 000
Please power off"

I applied the patch using two different programs and burned two CD-Rs at 2x on Taiyo Yudens like I always do, so I wonder if the patch needs a tweak for CDZs? I did apply the copy protection patch, so that's not the issue. Could someone burn the ISO that I made and test it on a regular NG CD?

Yep. Very cool. My copy hasn't left my cab since I got it. It's not perfect. There are a few areas where things glitch visually or audibly, but it's so much better than the original 2. It's somewhere in between 2 and X's speed, and in some section I actually think it's faster than the equivalent area in X.

Just an essential fix. So happy it finally saw the light of day, and every little hiccup it makes, and they are minor, is nothing compared to how awesome it is to play. Can't believe it took the community to fix this, but, how awesome is our community? Pretty freaking awesome.

My main problem lies on the game not getting along with memory cards, once the countdown starts and you let it go it doesn't follow to the gameover screen, it just stays there at the end of the countdown...take the MC out and you're all set, kinda of a bummer...

Other problems like glitching and whatever hasn't happened to me, beat it with BustedStr8 credit feeding co-op just to see it in action, no issues, everyone else having issues should check their PSUs, any voltage problems on multislots is always going to get you no matter the game specially on boots or homebrew stuff...

Yes, there is defo an area where the engine can be sped up. If fact I would say if one patched the engine correctly then the way this turbo version gains speed can be removed. It causes unwanted glitches because its not actually doing what the guy who did the fix says its doing (not system11). Not to take away from it though because those glitches are quite minor compared to the playability added.

Sure, it would report why the system is crashing. The turbo speedup does not work like the creator stated although I can see why they assumed it does. It does not surprise me at all that it would cause instability due to that's its actually doing (breaking required sync between the game play routines and the graphic drawing routines).

I think Mission 2 is one of the stages where X really stands out above 2. Mummy dogs are great and the descending mummies. Not to mention the slowdown on the boss really kills it, it got really frustrating. I played 2 this weekend just because I happened to grab it to test my new Unibios install and just felt like Mission 2 was missing a lot, including some hidden items. I know this is an endless debate around here, and I know you didn't do this, but I really don't get how people can defend the slowdown as a positive thing.

I think a more extensive but productive mod would be to restore Metal Slug 2's palettes in Metal Slug X

This would be so awesome.

How does an overclock compare to this patch? I know OC'ing an MVS cause glitches in some games, but iirc not Metal Slug 2, which is really the only game where it's really worthwhile.

Exactly this. If you could swap the color pallete then I'd give more gameplay to X. But yes, the pacing in spots is horrid.

I was actually thinking that as well... It creates some drama & adds to the tension IMO.

That's how i feel. I know people hates slowdown in MS2 but i feel it's quite fun: watching character moving slowly & jumping between stairs and boss machine in a slow-mo :)

I like MSX but for odd reason MS2 & MS4 are the two i play the most..........

The theme of people who prefer 2 over X seems to be "X is too hard for me."

Absolutely.

And more mummies = more points to milk. :buttrock:

Removing mummies from MSX?! Really?! Pallete? OK fine swap your pallete but gee mission 2 in MSX is pretty easy as it is, WTF is the problem there, you people are weird. Keep your slo-mo...

WTF?

I don't understand the confusion. I'm arguing that Metal Slug X's second mission has extra mummies littered in it to give it fake extra depth. It isn't making it any harder, it's just wasting more of your time by throwing more in your face. In the same way, TMNT: Hyperstone Heist for Genesis isn't harder than the other games in the series because it has more enemies, it's just more work.

There are other changes in MSX that are fine or even good, but I won't agree that adding spam to mission two is one of them.

Electric Grave

Really? They add some but take away others, so I don't think it should take you much longer. Mission 2 is fine the way it is in MSX, to me it just comes across as nitpicking, not enough to worry about.

Never heard that honestly.

I'm one of those 2 > X guys and I say so because I prefer the original design over the new weapons, enemies and swapped bosses.

MS2 is perfect as it is, but sometime the slowdown is a bit too much.

Using the MSX engine to reproduce MS2 would be a nice experiment.

I actually agree with that. The things that bother me the most with Slug X is the strange new colors that they used for the backgrounds, (the purple sky on the train stage is most strange of all). The bosses being swapped around was really unwanted, and the added guns were okay, but only about 1 of them was really amazing to me.

As far as Slug 2 over Slug X is concerned, I think that if Slug X had the same amount of slowdown that Slug 2 had, more people would easily prefer Slug 2 over Slug X. The only thing I really liked about Slug X at all, were the dog mummies. It's a shame that SNK did not just use all that extra data in the ROMs that they worked on, and at least made one new final mission for Slug X with all new enemies, and bosses, similar to Slug 3's end stage that takes 30 minutes to beat. That would have made me like Slug X much more, but as the game is, Slug 2 was just better and felt more natural, although the slowness of it has annoyed me since the day it came out. ugh..

I always wondered if MSX was a replacement for MS2. By that I mean did SNK send them out to Arcade ops pissed at the performance of Slug 2?

Before I head to bed I decided to take a quickie look at metal slug 2 in the debugger:

Not sure why it's doing this. It's writing an incrementing value to the VRAM Read register ($3C0000) repeatedly. Many similar routines are called in a row. Anyone know what's going on here?

It is updating VRAM to display graphics.

Very Kool idea an extra stage that was built from the ground up for X would have defiantly made it stand further on its on ground and been a nice lil bonus, it could be a normal length level as far as I'm concerned

I did know one Operator in NYC back in the day that told us he got X sent to him when he actually called SNK to complain (was notorious for complaining)

I just had a quick look at the code you pasted. It can defo be done quicker, in fact that code can be removed with minimal damage given all its doing is clearing the unused sprite tile information (which may already be clear).

I gave it a quick try. Patch P1 ROM from address 0x7F53C to 0x0060 0xFA00 (a branch to end of the table, byteflip the patch values if you do it in the MAME debugger). It causes some issues when sprite shrinking on the title page (metal slug 2 text) but apart from that game play looks unaffected. Not sure how much speed is gained however but it may be noticeable given this routine is called during gameplay.

It certainly was not for free for AES users as I remember when SNK called me to tell me their "NEW Metal Slug that was available to order" when it came out, and I don't recall any of the arcade's around my area getting Slug X after having Slug 2, so I doubt it.

I guess I'm not familiar enough with the Neo-Geo system architecture to know why that code works. Does writing to the address register implicitly write to VRAM as well? Is there no DMA unit to copy a sprite table into VRAM?

Razoola
04-06-2016, 02:53 PM
Nope, there is just a few ports from 0x3C0000

mikejmoffitt
04-06-2016, 04:58 PM
Interesting. How does writing to the address register copy data, though? I would expect you would write to the address port once to set the address, (optionally) set up an auto-increment, and then write the data itself to the data port. Am I just out in the sticks here?

Razoola
04-06-2016, 11:26 PM
Yes that is what it is doing. The first word of the long word is the address and the 2nd word is the data. In this case its filling VRAM with 0x0000

I've been playing with this lately too, and it's better than I thought, especially in 1-player! Played through a full game on 2-player, and it can still be a slowdown fest, but the kind of slowdown that remains feels more natural and forgiveable.

I noticed some new graphical glitches on the title screen and stage clear screens on my MV-1C, but nothing major.

I wish they didn't change the title and NGH # though. This is an official cart that I felt bad about desoldering. I know it's nitpicking, but I'd rather keep my official cart as stock as possible.

hello mate, im in the uk, I have a eeprom burner to do this and would be happy to help.

And yeah MS2>MSX
