I just (as an experiement) copied my copy of gt4, it's 5GB so I needed a dual layer disc... Using 4x speed (never let me down yet) I burnt this...but the copy only goes up to the copy right screen. This is the first time I made a copy of a large ps2 game, is there anything I might need to do to make this work on my chipped ps2 or just assume it was a bad burn? The disc is a TDK dvd- R dual layer, TDK has never let me downyet...though I wish not to waste such an expensive disc
