Neo2 Some but not all???

[Hocus]

Installed the neo2 into my USA v1 Playstation 2 ...chip looks to be working. My old copied psx games boot fine and my orginal ps2 games do too... but the only way to get ps2 backups working is to do the Game Shark2 spinning swap like you do with the EA games...I have pushed the reset button for 2sec,3sec,4sec anything more and the cd will eject of course..and they will not boot choosing start game w/code pop the gs2 cd out and put my backup in..makes a little sound like its trying to start but nothing... I have copied my SSX, Madden 2001, R2R2, and they work fine using the EA boot but nothing else I have tried works Starwars starfighter, winback, Ridge Racer 5.. I have used clone cd and cdrwin3.8d ....I reopened my ps2 and #####ed the wires and all looks good.. HELP!! Thanks
