Hi. Do anyone have any idea Kozarovv found these offsets for the 4-player patches (see the mtap related code in the spoilers below)?
The PS2 emulator can't handle inputs for games that require multitap to be connected on port 2, these are seen as controller 2A, 2B, 2C, 2D and are therefore not read.
Kozarovv solves this by finding offsets for these inputs and redirects them back to multitap 1 in this order:
2A -> 1B,
2B -> 1C,
2C -> 1D.
I would love to know what tools being used and if there is certain function calls to look for in memory by using cheat engine or similar.
If you have any ideas how this could be done I'm all ears since I have a favourite game on my own that have the same problem (Sega ages 2500: Decathlete Collection [SLPM-62444]).
Example #1:
Def Jam™ Fight for N.Y.® NTSC (4 Player fix)
Example #2:
Urban Reign™ NTSC NTSC (4 Player Fix) +Cheats)
