- properly set up MMU tables with caching and other fun stuff - maps a regular ARM-style exception vector table instead of using the bootrom vector redirection features a ton of bugs because I'm missing something, it actually manages to boot fb3DS v1.2 and BAX fine, but fails to boot itself 2019-04-15 21:27:35 -03:00			`#pragma once`
