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.

You’ve got my attention

That was the orignal motivation :) (was considering using the twlfpga but I need more I/O).

I'm trying to spec it so I can throw some PSRAM on and meet timing while holding a full 32MB of ROM data.

@byuu_san might also be interested. Pretty sure you could simultaneously probe ~every bus on a SNES.

I think @gekkio might have something like this for the DMG.
