Brainstorming an open FPGA breakout/devboard design with lots (>100) of I/O and USB. I should start writing a design doc soon...

Use cases: system probing/reversing, cartridge emu, massive I/O (LED screen?), logic analyzer, memory dumping/programming.

E.g. daughterboard provides 5V level translation, then uber cheap PCB-only frontends interface to every retro cartridge connector ever.

Stick it into a console and it's an emu w/logic analyzer. Put a cart slot on it and you can use it to dump. Enough I/O left for capture.

For GBA experiments I could hook up the entire cartridge connector, LCD connector (video capture), buttons and audio.
