    Hi all, new here and have a little question, I have an old playstation version schp 7502 board is pu 22, anyway I played many backup discs on this and never had problems, until after being put aside for a few months, I eventually get it back out feeling nostalgic and try to play a few games, but it won't recognise the backups, so I think to myself maybe the chip is loose, so I take it apart to look, and no chip??? No sign of wires, so how was it possible to play backups before?? I never used any other hardware or the swap trick so how was it capable of playing backups'??
