gba-bios

A Game Boy Advance replacement BIOS. Written completely in ARM assembly from scratch.

Accuracy

This is mostly a fun project by two programmers, therefore high accuracy is a non-goal.
But we aim to make it compatible with most commercial games.

TODO

• implement remaining BIOS calls (mainly sound functions)
• handle attempts to read BIOS memory in all BIOS calls
• test BIOS against more games / fix bugs
