What's possible with Xbox 360 mods?

I know of the dvd drive firmware flashing to enable back up games to play, but I’ve heard rumors that complete home brew software has been accomplished. Any news is appreciated.

You can find much better info at http://www.xbox-scene.com/

Under the Tutorial section or the Forums section.

I can BS you here, but on that website you can find the guys that are actually getting the stuff done. I dont think homebrew is full on right now, but BenQ support is advancing.

homebrew is possible if your’e willing to setup the XNA stuff and build the games yourself

but you can do that unmodded already.
