everdrive-cfw

everdrive-cfw is a custom firmware which can replace GBAOS.gba on Everdrive GBA flashcarts. It is currently incomplete and mostly experimental. Uses a subset of ChaN's fatfs along with the official GBA Everdrive IO library.

Components

• loader_mb: For use with STLink v2 multiboot. Replace GBAOS.gba with loader_mb_mb.gba to chainload main via link port.
• main: Replaces GBAOS.gba
• build_tools/generate_fonts/font.vwflen.bin and build_tools/generate_fonts/font.img.bin: Place these in GBASYS/

Building

Requires devkitARM and libgba. Read through test.sh and upload.sh to get an idea of how to build and run.
