Hey everyone. This is my first post here. Some of you may know me from the GameCube homebrew scene. Anyway, this post is not about the Wii or the DSi. It’s more of a vintage hardware hacking post.
The Nintendo Gameboy Color was released by Nintendo to the public in 1998. Since then no one had dumped its internal boot ROM (the first code that runs when you turn on or reset the system). After spending a few days glitching the GBC CPU voltage supply and clock input, I finally managed to get it to spew out the contents of this initial boot ROM.
Read all about it (as well as download the binary and an almost complete commented disassembly) on my website here: http://www.fpgb.org. The website is mainly a blog about my FPGABoy project, which is an attempt to design a complete clone of the original Gameboy hardware on an FPGA.
Or if you are too lazy to click on the GBC Boot ROM link on the right of the FPGABoy blog page, you can directly hop to it here.
I also dumped the Super Gameboy’s boot ROM about a week or so back, which you can also read about (as well as download) here.
I hope it’s at least mildly interesting news albeit being related to an ancient console. 🙂
