Metal Gear Solid: Peace Walker

[ValentineVxx]

I Have a question, i have a EUR copy of the game, it worked very well, but since the PW II Bug, i had to search for a USA ver copy. Luckily i found one, and was able to use the CwCheat to pass throught that mission, but in the next one, PW III, when i end the mission, the emulator crashes, i swapped back to my own copy of the game and i could do that mission without problem. So my question is, does the game crash on USA ver cause its a little scratched or by other reason? 0.o
