NICE TUT i need to try this

yeah nice tut. but sometimes when i download the iso/cso when their done it say they an unknown file or damaged. anyone know why?

yes this helped me out a lot thanks and this definatly should be stickied

That's because their damaged/corrupted. You'll have to redownload them, or start downloading them from a more reliable source.

def need to try this once i get my PSP back.

I play ISOs fine but when i play a CSO it laggs a little is that normal?

Fabian try running at 333mhz in game.

you could just do this in the VSH menu if you have M33 firmware just change the UMD ISO mode to normal for UMD mode and either M33 driver or SONY NE9660 for NO UMD mode.

but......i dont have to do half of that lol all i do is download the iso or cso and drag them to my iso folder....then i can play lol i have a 3.90-m33 cfw so idk why i only have to do 2 things.....
