How to make a progressive scan hack?

[Red_Tv]

Hello I want to make a progressive scan hack for devil summoner raidou kuzunoha vs. the soulless army and Devil Summoner 2: Raidou Kuzunoha vs. King Abaddon
consider the fact that nocturne DDS1 DDS2 DS1 and DS2 run on the same engine and the hacks looks similar to each other 
I think the only thing Inedd to do is o find the right address for DS1 and DS2
How do i do that?

// and leaving menus.

sceGsResetGraph can be easily found by file that have this label. In ps2dis just import labels from any elf that have that function described, then jump to label. About other patches, this gonna be hard using free software. You can compare executables for similar calls near patched area, etc.

If game engine is the same, and they not changed function too much. You can try search for hex sting close to patched area, then search for it in your executable. Is easier with some professional disassembler, but if you need to ask.. You don't have it.

Try this :-), should allow you to find sceGsResetGraph & 480p patches, you can also patch the Video Mode address for NTSC2PAL or PAL2NTSC codes.
