Firmware 1.00 to 1.50
Homebrew for Firmware 1.00 to 1.50 can be loaded directly from the PSP XMB. Homebrew games should be placed in the “PSP/GAMES” folder of the Memory Stick. Some games may require certain steps in order for the game to work, please see individual games for more details.
Firmware 2.00 to 2.60
Homebrew om Firmware 2.00 to 2.60 can be loaded in two ways, either using the TIFF Exploit by loading a image from the XMB or by using the GTA Save Game Exploit. Both these methods allow the use of a EBOOT Loader that again loads games from the “PSP/GAMES” folder of the Memory Stick. Not all homebrew games are compatible with these firmware versions.
Firmware 2.70 to 2.80
With Firmware 2.70 to 2.80, homebrew can be loaded using the TIFF Exploit. If you are using 2.80, there is no EBOOT loader available, and as such, only a limited number of games are available. If you use Firmware 2.71, you are able to load homebrew directly from the XMB using a hack.
