Can you use FIQ mode to switch between two sets of registers on a GBA/NDS?

Yep. I mainly used it for sound mixers, although I never actually came up with an algorithm that was faster with the extra registers.

isn't there a bit you have to set in the nintendo logo addresses to enable the "undefined" and "fiq" processor states on the GBA? check out cowbite or gbatek...
