anyone ever seen a snes sfx-multichecker?

Thanks! The button is for the battery check? I'm curious about the 74125 (4-bit tri-state buffer), that seems out of place. The A14-13 are for 256K SRAM limiting down to 64K I guess, not sure about the other switches. I think the unpopulated IDC connectors are just test points, probably don't serve another purpose, generally Nintendo test traces lead off the board.

I expected a bit more from this cart with all that logic! They could have easily implemented every official board type up to 64M.

 

I love that Donkey Country Exposed Video, its amazing it shows so much stuff I wish I had access to.

 

I don't know what the button's for yet. I plan to play with this more when I get the chance. It very well could be the battery check and if so, the battery is dead...
