Could you build this?

No Writing a clean-room, bug-compatible GBA BIOS requires low-level ARM7TDMI assembly programming and exact reverse-engineering of cycle-accurate math routines and interrupts.

What it would actually take: Development requires deep expertise in ARM assembly, the Game Boy Advance hardware memory map, SWI (software interrupt) routines, and decompression/math algorithms. Testing relies on comprehensive hardware-verification test suites (like mGBA's test suite) run on bare-metal hardware and emulators.
