PS2 Doesn't play ps1 backups or original games

[UrrBodyH8sMe]

i belive its the cd speed to read ps1 games has to be set on a dif speed from ps2 games but yet it plays ps2 rips on cdr yes but its reading as if it was a dvd just smaller so there for it wont need to read as fast as a ps1 game or rip i would try checking the speeds in ur opition first and work from there i have had a ps2 b4 that would only play dvd games no cd based games i had to send it to sony and they fixed it for me for free
