gba-flashcartio (2024) 🔗

A Game Boy Advance (GBA) C library to access the SD card of the following flashcarts:

• EverDrive GBA X5 / Mini
• EZ Flash Omega / OmegaDE

The flashcart type is autodetected and FAT partitions are supported via ELM-ChaN's FatFs library.

• Only read operations are implemented in FatFs.
• It reads using either DMA3 or DMA1.
• In EverDrive mode, the latter 16MB of the ROM is unavailable while reading, so avoid using that part in your interrupt handlers, or your code might crash.
• In EZ Flash mode, ROM is unavailable while using the SD card, so ~1KB of static EWRAM will be taken by some functions. Also, When reading, interrupts will be briefly disabled (REG_IME = 0) to avoid problems.
