Prototype vs board?

Prototype vs board?
by on (#134491)
Hello,

I recently acquired this "prototype " Vs. board to use in my red tent. Basically, instead of using the vs roms, it has 2 famicom slots to load famicom cartiridges in. I have not been able to find any information regarding this board, and am currently having issues with controls and starting games ( though the games do load, I can not get them to start.

Any information is appreciated.

Many thanks!

The Vs. System's controller ports are swapped. Use controller 2, and use an AV Famicom or an NES-JOINT adapter if you can't use player 2's select and start buttons on the original RF unit.

Those aren't "famicom slots", and they most definitely do not connect to Famicom cartridges - the first edge connector shown is 44 pins, and the second one is 36 pins.

Can we get a less zoomed in shot of the PCB?

So whatever is the case, it does seem like the games are working.

It's not a prototype board. They were common in Japan and other countries and there are few different varieties. There is no documentation available except the VS schematics and common Famicom knowledge. You are going to have to have to troubleshoot it by hand.

I want to know what the solid state relay is doing on the little daughterboard above the PPU, and what the board is even for.

The daughterboard is where you plug the famicom games into. You just can't see it in the pics.

I'm not sure about this particular board, but usually these boards are timer based. You pay for a certain amount of play time. Another CPU or other hardware is in charge of locking out the user once the timer expires. The relay could be for that. Sorta like a Playchoice except one game per side.
