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.

More proof that 2 > X
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.

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.

My YouTube channel contains some MVS repairs and stuff:-

With a 16MHz overclock and the patch, the game is smooth as butter. As good or better than stock MSX in the frame rate department.

<S.Yagawa> I like the challenge of "doing the impossible" with older hardware, and pushing it as far as it can go
<T.Fuzisawa> Think of something that has never been done and make it a reality.
Nice work! Do you think it would ever be possible to sub in the entire Slug X engine so no OC is needed?

Fucking sweet. Thanks a bunch to you and your team for helping with the slowdown in MS2. Looks awesome. You guys already made my year.
Nice work! I'll have to let my friend know about this, he loves that game.
It is now time to crack open my Slug 2 carts and give them the engine facelift they so desperately need.
Thank you kind person for taking pity on the rest of us!
For those curious about what exactly the problem was and what was changed to fix it, I wrote a technical explanation of things: http://daifukkat.su/blog/archives/20...ts_turbo_time/
Forgive how terse and technical the writing is, but I tried to give a decent explanation while not leaving out details.

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.
