like the pin outs. i found SMS and NES and Gameboy cartridge connectors in bulk but they seem to raise eyebrows when I say Sega Game Gear. was it called something else in Asia? what are the pin outs to make it easier to find ask for
Unfortunately I don't have my Game Gear around at the moment, so I can't give you dimensions.
Edit: Open source SMS to GG adapter: https://github.com/ms2gg/pcb/releases
This includes the Gerber files, so you can measure the connector from there.
(This is the opposite of Apocalypse's design, as the SMS is a subset of the GG hardware.)
I just joined today to share a lead that I had for Game Gear cart slots.
(It gave me the reason to join. I've been reading on this forum unregistered because I want to restore a PlayChoice-10).
This project was mentioned on www.retrorgb.com recently.
Unfortunately, it is sold out as of writing this but... I can confirm that it will work.
I bought one to use on my RetroN 5 3-in-1 adapter when my GG slot on it cracked.
