ok, i successfully backed up Need for Speed Underground on Memorex media, and it worked like a charm on my version 7 playstation2. I brought it to my friends house who has a much older version, and it seemed to play fine but there were so many weird glitches, like after a turn the road would turn into the sky and it was really messed up. what is the problem here? weak laser? i'm really confused. Also on his ps2 espn football played fine, except the intro skips everytime. and you have to wait like 2 minutes for it to load up. and in the game it gets slow and choppy at some points. same with smack down . but all of these games work fine for me!! what is the problem???
