MDR c`est bizzare!sur certaine console il y a des ralentissements...d`autre c`est les menu...d`autre impeccable!
c`est pas du HD:Guys, all this cheat does is increase the buffer size for the graphics engine. The "option" that they are referring to is the "Progressive Scan" option in the menu. If you´ve already been playing with that option on, then all this will do is slightly increase the buffer size. That translates to slightly better graphics at a slightly lower speed.
You know the cheat worked if the first legal SCEA Presents screen comes up in purple.
To be honest, the change is VERY VERY slight and hardly noticeable. (At least on PS2, not sure about PS3)
