I recently (last week) received a premodded ps2 with the matrix infinity installed. As i began to back up my games, i noticed i was having trouble with some games. In ssx3 the mountain backgrounds would rapidly switch, in spiderman 2 terrain acts like an earthquake, and in nba street vol.2 the characters are flashy and pixelated. Today just to see i tried the original discs and the same results happen with the originals. Whats the deal?!
