Bump! Still available, here's a little more info.
Vs. Gumshoe was one of the last games made for the Vs. System, and as such needed a 'memory expansion' mod to the pcb's it was placed on. Basically, you just add a couple jumper wires to a Vs. pcb... it makes it play the 'newer' games, as well as all the regular Vs. games. So you can still use this pcb with any other game, but it has the two jumper wires added to it to allow it to play the newer ones as well. I'm not sure which other ones needed those jumpers.
It's a gun game; and it's pretty unique in that it's PPU chip is specific to this game. You can't do a rom swap to play this one, this is the only game that uses this PPU.
Boardset was tested working, and the chips work on both sides, both sides of the board have the mod. Also the game is a gun game! It's pretty fun, and a little obscure, you don't see it too often.
$80 shipped including the tested working board, ready to go in your cabinet.
