hi y'all i just want to know if there's a way to umd recognition in psp using iso or cso format.

because i have a game here called yu gi oh gx tag force 4 and it needs some umd recognition to its previous version to unlock in game functions like booster pack and character..

but i dont have any UMDs i only have the iso and cso that i downloaded in the net

i already tried searching answers on my own and i found out that CWcheat would do it. but i think its to risky in my part.

is there another way to use umd recognition using iso or cso if theres non..

what is the guidlines to install CWcheats in psp safely.

i have genx full sofware in my psp 3000
