Homebrew includes any games coded by non-sacntioned developers for the psp. Homebrew does NOT include games created with a license for the psp, such as ISO "backups" of UMD games. You can not play ISO's on anything above 1.5. Some homebrew does not currently work on 2.01+, you can check
www.fanjita.org for a list of working EBOOTs (executables) for the each version of the loader.
Feel free to PM me any other noob questions you have if you don't want to post something that might get you flamed out in the open forum
