    Given that the Zilog Z80 CPU from the original Game Boy/GB Color (or whatever custom chip Nintendo used) was present inside of the Game Boy Advance and - supposedly - used outside of GB/GBC mode as a co-processor for minor audio-related tasks... where does that leave AGB_firm on the 3DS? Is the Z80’s instruction set completely missing from the system, emulated/wrapped on some level or did they quietly stuff it inside of the ARM7’s silicon?

    if i remember correctly the z80 was removed from the gba micro and all of the nintendo ds line up to and including the n2ds xl, could be wrong tho
