Please turn on Audio.
Besides the japanese set any others you want to be included in this release?
very nice. i know it’s supposed to be a patched rom so you can burn to actual cps2 if you wanted, so I’m not sure if there is a way to make p2 stays in crouching position like the pof mame cheat (but then there is no mame cheat menu in patched rom).
Most solutions will involve a rubber band, but i’m only using one of 3 known jumps to 10efc. Someone could hack in a menu eventually.
Also, Xcopy isn’t good at decrypting.
What problems does xcopy have? I’ve put some simple asm hacks in the ssf2t rom with it without any problems… it worked perfectly
It’s Decrypting a part that isn’t asm.

I keep checking if anything is wrong even used the custom encryption option to see if it was a wrong key.
And yes I need 80 bytes for asm.

If you’re wondering how this problem didn’t pop earlier.
I do asm in the memory like the unused network memory(0x660000 - 0x663FFF). Optimize, till I can’t get rid of anymore code. Then find a place in the rom for it.
If that proves to be a big issue, I should be getting a dead SSFIIX in the next few weeks, which I could put Avalanche EEPROMs in.

Just posting to notify the Avalanche JP AM set is up.
And I do test the roms before making patches.
Even the Avalanche roms. 09 is giving the error since there is no boot up menu on avalanche’s set.
Hey @jedpossum, can you post the patch for the encrypted ssf2xj rom set as well? it’s useful for playing in ggpo’s unsupported room.
Is this for all cps2 games? After testing some custom drop patterns on Dreamcast puzzle fighter, I was thinking of hacking them in the puzzle fighter arcade rom…
How did you get this information? or how would I go about figuring this out for puzzle fighter?
You can look above and see the problem of doing an encrypted set. Even using Xcopy on the avalanche ST Roms doesn’t solve the problem.
Mame Source, messing around with said games, and Razoola’s notes on making a phoenix set.

The Graphics memory(0x900000-0x93ffff) area can and will be quite different with each game.
Edit
Example
Vsav
0x900000 8x8
0x904000 32x32
0x908000 16x16
0x90C000 Palette Bank
0x918000 Dark Force 16x16
0x91C000 Dark Force Palette Bank
Notice the Hud isn’t stored in the graphic memory.
Trace of the SSF2 Tournament Battle Terminal Check

Interesting note there isn’t a check in the network memory.
Sorry, didn’t see this part earlier.
I would find out what is dropping the blocks and trace back till there is a command reading the player’s character and multiplying by how big the table is to get it’s slot.
Thanks.I’ll give it a try, as well as razoola’s notes a read.
@felineki
Well, I only changed one byte. My first thought was swapped roms with itself or ssf2. but looking at the description that is wrong.
Also, I’ve been meaning to get a hold of you on the rom joiner you used. I want to make better collision brackets in ST eventually.
Have it like vsav’s boxes or kof.
It’s been ages since I messed with that, but I think I used WinHex to split the original ROMs up, and then the interleave tool found here to paste them together in a way that Tile Molester could display them properly. I never actually got around to trying to modify something, rearranging it all back into the original ROM format, and then seeing if it would display properly in the game or not.
Hmm no easy way to get rid of the interleaving after it’s done. Ah well, atleast it was something I wasn’t plan on doing any time soon.
Did Capcom mean for Evil Ryu to be in ST before being in SFA1? Check this out…
