Hi everyone,

I have questions about three PSX Capcom games:

Darkstalkers 3: I recently found out that Donovan has his newer improved sprites from Vampire Hunter 2/Vampire Savior 2 in this port, but they only appear if you choose the D.F. Power mode, how do I make them be his default sprites?
Street Fighter Alpha 3: Is there a way to turn off regulation mode, so the red blood can appear on everything once again?
Pocket Fighter: How do I re-enable the Japanese voice tracks for the story cutscenes, they're still in the BIN file.

What hex values do I need to change in them, in order to do all that?

There's probably multiple working solutions for each problem, but knowing a little bit of ASM will probably get the best results in all cases.

For Darkstalkers 3, you can probably just replace the "normal" textures with his "improved textures" so that it gets the improved sprites regardless of what it tries to load. It's not the best solution out there but it's pretty simple to do without ASM.

SFA3, if there exists code for "regulation mode off" but it's just inaccessible a simple Gameshark cheat code might be able to enable it but you'd have to do some digging.

Pocket Fighter, I can't imagine anything short of reverse engineering what code loads the voice lines and redirecting them to other desired files would do.

For texture stuff, give tim2view a try for seeing what textures each file contains and replacing them. For ASM stuff, try mednafen or PCSX-R for emulators with real time debuggers. Either way, psximager will be handy for ripping the files out of each game, and injecting or rebuilding the disc image with your newly modified files.

Thanks for the info, but unfortunately I'm not an expert on debugging, along with using ASM as well.

Sorry about this.

I'm not really either. I just beat my head against a wall until I finally kinda understood what I was doing. Give it a try, maybe it won't make sense this time, but if you come back to it and try again, you'll get it eventually.
