GBA Cartridge Reader

Hardware and software for an RP2xxx-based Game Boy and Game Boy Advance cartridge reader that presents the contents as a USB storage device.

Board

• board contains the "v1" PGA2040-based GBA-only board
• board-v4 contains the new RP2350-based design that also supports Game Boy carts and can theoretically be expanded. (to be added when I make the fixed version)
• (v2/3 designs were never made. For completeness v2 added the Game Boy support, and v3 was a custom RP2040 design)

Case

• "v1": https://www.printables.com/model/972096-gba-cartridge-reader-case

Software

For the old RP2040-based boards, just build like any other pico-sdk based project. For the RP2350-based board configure with cmake -DPICO_BOARD=pico2 -DPICO_RP2350A=0 [...].
