Kodewerx

in one of my PS2 games a character mod is not able to load boss's or enemies (aka meaning you cannot play as them) attempting to play as them always results in a crash. i found a way to bypass this by disabling the "v0" (vector unit) register. but here's the problem, the code works very nicely on pcsx2, but when i try it on the actual PS2 it freezes before any textures can be loaded.

can anyone think of a way to fix this so it can work on the actual PS2?
i have tried jokering it but that didn't work =/
