Fixes most of the nonsense found here (such as the GBA BIOS being OK despite being the only real choice), although MSX bios_basic_usa is still split in two for whatever reason, but I did verify the TI83 roms (and removed the Plus ones that don't work atm)

Check if completed:

• I have run any relevant test suites
• I, the commit author, have read the licensing terms for contributors (last updated 2024-06-22) and am compliant
