ok. well i been looking at all types of external and internal mods. and by far i have not seen and L2 R2 mods fors psx games. i had an idea!
people who have taken out the umd drive kno what im talking about. there is a little "trigger" that starts the umd drive when pressed down. it is verry little but can be used in many places. i was wondering if you could mod 2 of them to make l2 and r2 buttons that are compatible with psx games!
