Way back in 2005, I entered my first Game Boy Advance homebrew competition with Drunken Coders (which doesn’t appear to be alive anymore) with a game called Santa’s Sweatshop. I didn’t place in the competition, but this was my first real game that I built and I did everything – including the coders artwork, and playing Christmas tunes on my guitar with tons of distortion! I even made up a story with a short cut scene between Santa and his new head elf.
I don’t know if I still have the source code for this but was looking for a download when I found this YouTube video:
Anyways – if you happen to have a gameboy advance lying around, or an emulator, download the game here.
