gba-flashcartio (2024)

👾 gba 🔗

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.
  • For this same reason, avoid soft-resetting while flashcartio_is_reading.
• In EZ Flash mode:
  • ROM is unavailable while using the SD card, so ~1KB of static EWRAM will be taken by some functions.
  • When reading, by default, interrupts will be briefly disabled (REG_IME = 0) to avoid problems.
  • The EZ Flash Definitive Edition works great out of the box, but in the original one you have to use 3,2 wait states and avoid writing to SRAM right before/after reading the microSD!
