Well, I can see the others on the list (Gururin, Puzzle de Pon, Andros Dunos) since no CD version was made, but his only downloadable is Joy Joy Kid which already exists in CD format. Seems like bullshit to me.

Are you Charles Doty, the game programmer?

Yes. I am also registered on the Neo Geo CD forum.

Have a look at the JoyJoyKid.zip file, burn it to CD and try it in a Neo Geo CD player.

Then have a look at the differences.

First of all the Joy Joy Kid CD I have has 41 audio track, the one on the site requires one.

The PCM files are different size, and there are a small number of differences in the PRG files.

You may also have seen some of the previous work I've done on the Neo Geo CD.

Compared to the games he's done these are huge meg counts and would likely require an extensive amount of work. I've seen requests for Ghostlop being converted to CD format would be interesting to see if that could be done.

Interesting work by the way would sure make the CD a more enviable format.

he probably made that one free, because it IS already released on CD, i think if he spent the time to convert them a little donation is worth getting the other files. pretty cool if you could convert every mvs game to play on the CD system.

whinny little kid, why r teens so angry, needs sec
maybe SSVS will see CD release now like that one nut wanted

hahaha

loading.... fetch a drink, make something to eat, go out for a bit, come back, still loading.... take a shit, come back, nope, not yet... etc

Hair Group,
Is this is real then great stuff, theres some real kol stuff that is CD worthy like MD3, Money Idol, Blazing Star etc.

Some blatantly cant be done, any are welcome tho really tbh.
 
this is great, good luck on your next projects.

I hope you have plans to do the opposite, fully working versions of the NGCD exclusive games to the ROM format.

This is tits.
fucking tits I tell you.

Top priority makes that need to be ported are:

Spinmasters
Ghostlop
NITD
Money Puzzle Exchanger



Others would be:

either of the puzzle de pon games
Captain Tomoday
Ganryu
The Irritating Maze
King of the monsters
Super Dodgeball
Zupapa!


and if it is even possible (since they are higher meg games):

Kizuna Encounter
Prehistoric Isle 2
Sengoku 3
Strikers 1945
Shock Troopers

I can only dream.

This rules. About time the Neo CD gets the love it deserves. Good choices there Orpheus, but I'd take MD3 over MPE.

Yeah, the only reason I put MPE as top priority was of because the aclaim that it has with neo fans and the fact that we already have MD2 oficially released on CD (with an amazing AST).

guys.......

Why pay for such a kind of stuff when those conversions were made and released a long time ago? Anyway this guy put a lot of effort in this and deserves it, you should decide that.

here is a list of conversions i did with some friends:

http://www.galeon.com/kanyero/list.htm

you can grab the dat from here:

http://www.eggmansworld.com/console.htm

All this conversions were released .iso format for all of you to enjoy with neogeo emulators like nebula or other using daemon tools. You can burn them directly too.

There is an explanation because there are sound or graphic issues in the first link (memory reasons).

For all of you requesting conversions think that all possible conversions with minimal glitches were done a long time ago,i didnt do those that were in cd format because they are not needed. I dont have enought knowledge to do conversions bigger than the memory ngcd has because here more that just a irq swiching is involved.

if you are wondering where my conversion are, all of them were relased for free in some unitedusers irc channels.

***Edit: now im uploading all of them to a host*** :glee:

hi again

@ neo_X7

those games are too big to fully fit in ngcd memory so its out of my limits, better forget about them sorry

about kotm the conversion is complete, just some sounds are missing due again to ngcd memory limitation.

I think that maybe if i can downsample the pcm samples quality i can rebuild the file again so i could add even more voices to the games, but i dont know how to make that. For z80 (m1) maybe it could be removed some useless data.

Don´t worry im uploading those files, even the non working games:

Not Working - eightman.zip
Not Working - diggermanv2.zip
Not Working - diggerman.zip
Not Working - bakatono.zip
Not Working - minasan.zip
Not Working - neopong10.zip
Not Working - neopong11.zip
Not Working - puzzldpr.zip
Not Working - vliner.zip
Not Working - vlinero.zip

Maybe some experts could fix some of them.

Im having problems with my conection so i dont know when could i finish upload them but dont worry, you will have some news during this week :)

no, i´ve been requesting a tester for a long time but it seems that ngcd is not very common here in spain.

another thing i was requesting was a loader so you can choose any of the games directly from the menu and burn only just one cd for all those games and maybe more conversions (those for games that have a real ngcd version and that i never converted because of that reason).

im still having problems, i´ve been able to upload some games but i still must upload most of them, i will try to finish upload tomorrow. cross your fingers :)

Well, I have actually owned two NGCD units, but sold them when I turned MVS. I think I know more people here in Barcelona who might have a NGCD, I'll ask around.

well here is what you have been waiting

http://www.speksnk.net/descargas/neocdconv/

please dont direct link to the files.

i just want one thing:

Please if anyone knows how to make better conversions just let me know:im interested in how to decrease v1 and m1 size mainly and how to fix those non working games.

Im also interested in ngcd to aes/mvs conversions, mainly in how to fix final romance 2 and how should adk workd and crossed swords 2 be converted.

another question im interested is make a frontend to store all those conversions in just only one cd.

Enjoy and tell me your experiencies, maybe more conversions will follow.

Cro ords, ,
I've just tryed to burn Zupapa (fixed version) and it doesn't work on my neo geo CD Z.
But, unlike the neo CD1 and neo CD2, ISOs don't work on the neo CDZ. So I don't know if the problem is due to conversion or to the neo CDZ.

I can vouch for cdoty, been a while though, I think were were messing with a Puzzle De Pon conversion to the Neo CD on the Neo Homebrew list, might have been 3 or 4 years ago? I had hosted an early version of it on a site I had then........
 

jbeedham

yeah he did that, ,
I am willing to try it out but what is this I hear with the CDZ? That is what I got and need to know if I need to burn it a special way or something. Do I need a boot disk (ala Dreamcast)?

No , better a CUE file than ISO

the newest games cant be played on CDZ

zupappa fixed version was fixed to work in nebula, the unfixed version worked fine en neocdsdl, i dunno if the original should work in real hardware (what was the problem???)

I dont know if any of those conversions work in real hardware.

Please post your comments here.

Who knows? :smirk:

maybe the oldest...

i will try columns later on my CDZ... great game on Genesis without a doubt , veeery veeeeeery addictive, colosal battles with friends...

Columns > Tetris :D

Columns was da bomb! I played that all the time on the Genesis. The music is cool too especially when it starts speeding up later in the game!

Im a lazy ass so didnt track back to the beginning but is it all that difficult to reverse this process to do NEOCD to MVS?

I realize some audio files may require downsampling etc. I'm mostly interested in NEOCD exclusive titles (those that never had an MVS/AES release).

For MOTW couldn't you just make it were it would only load the Characters and back ground data in to the system memory one match at a time?

It is possible, but usually much more difficult, very few games have been able to do so far, there exist some CD->MVS conversions like Zintrick. About sounds, all the audio CD simply has to go so this games don't have any music, only sounds effect.

mmmmh

adk world
crossed swords 2

zintrick was made
final romance 2 was made but the conversion is not perfect (it reboots)
samsho rpg COULD NEVER BE MADE because its size
neo geo cd special is nothing but some demos

the only interesting games to be converted are:
adk world
crossed swords 2
iron clad
but they are too complex for me ... but if you want you can try :p

@neo_x7 as i told before its not possible just remember what happened with aof3.... but feel free to try yourself :)
 
CD-versions of homebrew games would be really, really cool. CD-versions of commercial games are just copyright infringement imo. Beware!

Tech Support Moderator,
One of the sounds tools I created a while ago would allow you to convert the PCM data to WAV files, then you could do whatever you wanted to them (resample, shorten, etc), and convert them back to the Neo PCM format. I'm not sure if this is on my site or not.

You would need to modify the driver file (M1) to adjust the sample pointers. Back when I was pissing with sound (before we had our own driver), I was using a hacked Puzzle de Pon M1 that pointed to my samples. It was pretty simple to do once you figured out the data layout.

A couple things to note (at least for the YM hardware) is that the PCM data starts on 00 bounds and ends on FF bounds so in the data table, you would not see the low byte of the start and end addresses. For example, if the sample was from 0x42300 to 0x425FF, in the table, you would see 0x0423 and 0x0425. Make sense? It's been a couple years since I looked at this, but this is just something to get your moving. I'm sure I have my old notes somewhere if needed.

The easiest way to find address offsets for sounds -- hack MAME and update the YM driver to spit out the commands it receives. Then use the UNI-BIOS to play the sound sample codes. Look at the log file and see what addresses were written to the YM chip. This is the way I did it back in the day, but I didn't have the UNI-BIOS -- I had my own test roms. I would image the UNI-BIOS would make it a lot easier for messing with multiple games.

I haven't looked at any of your conversions (even my games - Columns, Poker Night, etc -- thanks for asking) but if they are not booting on real hardware, it could be a problem with the loading sequence in the IPL.TXT file, or file sizes.

I think it would have been better if you worked with Charles on this rather than trying to undermine what he is doing. At least he is making sure his conversions work on real hardware AND he has the capabilities of doing the patching that would be necessary to fix some of the common problems you are describing. You should be supportive of his work.

im not trying to start a war, if you see my first post i say:

"Why pay for such a kind of stuff when those conversions were made and released a long time ago? Anyway this guy put a lot of effort in this and deserves it, you should decide that."

Anyone that wants to pay for those conversions is free to do it, i just wanted to say that i could feel bad if i pay for a conversion and then i find that they were released for free before.

I will be glad to work with cdoty if he wants: my private message inbox is ready for him.

Sorry if i didnt ask for converting your games, if you want i will remove them. I added the license where i could find it (see pokern).

About testing: i dont have a ngcd or ngcdz and i cant find any. i´ve been requesting a tester for a long time. If you see some isos are more than 6 months old, but nobody wanted to help so i finally did a dat and sent the isos to some collectors that should spread them.

About Your m1 and v hacking information: looks very interesting i hope you could share it.

About the bugs: ipl.txt secuence is revised, all files are trimed to the maximum supported ngcd size, and all of them have been tested in the best ngcd emulators i´ve been able to find. I dont really know if they work in real hardware but they should. It would be great to make a compability table using different emulators and real hardware (nebula, neocdsdl, neocdsld DC, Ngcd, Ngcdz). The problem with sound is that most of m1 in aes are 128k while in ngcd only 64kb are loaded. The same problem happens with v roms: ncd only can handle 1 mb.

@ large : i think having roms without the real board is ilegal too. I think snk allows the usage of its material for fan made games (for example mugen). Since the games converted are quite old and dont have support, and there are not profits with them i think there will be not problems at all

I just made a Ghostlop coaster :crying:

The game loads all the way to 100% and then the system resets. It did this on both my top loader and CDZ. I'm still anxious to try cdoty's conversions though.
