PlayStation Portable (PSP)

"Homebrew" is in its simplicity, homemade programs.
Throughout history there made a great many homebrew programs to a PSP. It's everything from small game, Browsers

Network programs and anything else exciting.
If you want to see the story behind the "homebrew" press here it is in English.

If I have to highlight a few programs I use myself, it must be Pimpstreamer a program to install on your computer and your PSP, then you can stream movies / audio and pictures from your computer to your PSP so you do not have to put everything down on one's memory.
Another program may be IR Shell which is a different interface than the original.

I've had linux on my PSP and I've tried all sorts of programs on my PSP which has been pretty fun instead of just using it to play.

I have updated the "Links" which will hopefully be some pages with a lot of homebrew you can get down.

You can not use these homebrew programs until you have a "custom firmware" This I will tell you about one of these days.
