The EZTeam, the people behind the EZFlash range of carts have today released their FATLIB code.
This code should allow full access to the mini and micro SD cards for the entire EZFlash IV range of carts. This means homebrew authors can now officially support the EZFlash IV carts.
This includes:
EZFlash IV
EZFlash IV Lite
EZFlash IV Lite Deluxe
EZFlash IV Lite Compact
