In the Discord, KML discovered that one of the SNES MARIO CHIP boards has all the signals needed brought out to test pads at the top of the board.
I asked if I had permission to repost this information so here it is:

Does this CoB style cart also have more than needed (at that time) Ram ? Looks like StarFox2 running there which needs 512k Ram.

Maybe it's working because retron dumps the rom and runs it in an emulator. So it doesn't matter how much ram the cart has.
