[monteca820ce]

Got magic 3............ Boots dvd-r backups no problem
Ps1 cd-r backups no problem
Ps2 cd-r backups dont boot at all

Ive tried both clone cd and nero, all the settings were right and using tdk media just as i used on the ps1 backups.

anyone know what the problem is

Figured it out and is working fine.
