I was going to download some sweet homebrew for my R4i when I saw a part of a website for PC games the homebrew developer made.
http://www.pineight.com/pc/Right at the bottom there's a game called Tetanus on Drugs. It's a tetris clone like Rotris except a lot more trippier and gave me a headache :O
So maybe someone could review it on youtube?
Oh yeah, and a GBA version called LOCKJAW: The Overdose, as the other one is DOS or something.
