How to Play ISO Games on PSP Without Custom Firmware

The Sony Playstation Portable (PSP) is a portable game console that plays universal media disc (UMD) based games. The game disk holds a single ISO file that can actually be played on the PSP without the disk. Playing an ISO file on your PSP using custom firmware is common these days. Many people do not realize it, but custom firmware is based off of Sony's official 1.50 firmware. This means you can play ISO files without using custom firmware, and by installing Sony 1.50 firmware.

  Turn off the PSP and remove the battery and memory stick. Insert the magic memory stick that will hold the 1.50 firmware.
