If you ever feel like reliving a bit of your past the Game Boy Advance uses the ARMv3 instruction set. With an easily available flash cart you have a cool little portable system to develop on.

Nit: the GBA uses an ARM7TDMI that IIRC implements ARMv4T, which isn't a strict superset of ARMv3 (I think that's the first ARM that dropped the old crazy addressing). Still very fun to mess with.

Sorry about that! The ARM naming scheme confuses the hell out of me. I always mix up the processor generations and instruction sets.
