Hacking the PSP - Homebrew Central

If you're new to homebrew on the PSP, I suggest you download my tutorial here.

Homebrew software is software that has been written for use on the PSP by independent developers and is not distributed on regular UMDs. There are hundreds to thousands of games, utilities, applications, exploits, and more available for free - all you have to do is download them. It's not piracy, although there are applications out there that do that sort of stuff, which sucks since it gives the hard-working homebrew developers a bad name, even if they didn't write the applications which encourage piracy.

There are many different firmware versions out there, since Sony continues to upgrade the PSP. In order to run homebrew on your PSP, you will likely need a launcher. Launchers run the homebrew applications off your Memory Stick. You'll likely want a higher capacity Memory Stick once you get into homebrew, as you'll download many games and utilities and they'll fill up the 32 megabyte unit that comes with the PSP Value Pack.

You can find many homebrew downloads in the Hacking the PSP Homebrew Software Library. Of course, you don't have to just run homebrew - you can write your own.
