hi there i have a slimline ps2 model no scph70003 PAL, with a matrix infinity v 1.38 chip, the problem im having is some times my back ups wont play ? i get that damn red screen and at other times the same game will load no problem. A way round this i have found is put an original game in for about 5mins switch off ps2 then insert back up and this does the trick. BUT WHY is my ps2 doing this ? and is there a way 2 resolve the problem ?
