Open source SMC proof of concept for the Xbox 360.
Buildable using the fully open source SDCC toolchain.
Currently this only blinks the debug LED but more might come.
This code currently only works with the Winchester motherboard.
The Xbox 360 relies on the SMC for fan control and thermal shutdown.
There is absolutely zero guarantee (per the GPL2 license) that this code is fit for purpose and that it will not destroy your CPU or make the console catch on fire.
USE AT YOUR OWN RISK.
