how can i put isos into my psp ??!!

hi every one i need help pleashow can i transfer the iso file s and work them on the psp ??
thanks everyone

Your PSP must be hacked and use custom firmware first.Then all you have to do is to put the ISO files in the ISO folder of the PSP.

If you don't have an ISO folder, make one in the root of your memory stick.

You need Custom Firmware. If you don't, then you can't play downloaded games.

what everyone said. The iso folder goes on the root of the card
