Rise from your grave, Nintendo Vs.!


Recommended Posts

Had a Vs. boardset with Vs. Baseball on it, which takes up both sides - 2 CPUs, 2 PPUs, and 12 EPROMs for one game... but it looked like a mouse made a nest on one side - corrosion city.

 

Removed the following corroded components, mostly from the right side of the board: 14 logic chips, 10 sockets, and 2 RAMs. I cleaned the board in the sink with liquid soap and very very hot water with a quick rinse and pat dry with a lint free cloth before putting it in the oven at 170F to dry. (170F is the lowest temp) Afterwards I inspected the board and found one open trace and a missing transistor, Q16, in the green output.

 

After cleaning:

I then installed the following replacement chips and sockets: 2x LS32, 1x LS00, LS74, LS04, F04, 2x LS138, LS245, LS373, 2x LS157, 6116 SRAM, and 6264 SRAM. WHEW. Then I installed sockets for the 4 Program ROMs, 2 Graphic ROMs, CPU, and PPU before patching the one open trace and installing a missing transistor in the Green color output for the right side.

 

After replacing parts:

Vs. Baseball requires both sides of the board and the PPU for the right side was trashed by corrosion. I didn't have another PPU of that type so I had to change the games on the board. I programmed 6 replacement ROMs for Vs. Pinball and installed that on the right side, them moved the CPU and PPU for Vs. Baseball to that side. I installed a PPU and CPU on the left side and programmed 6 replacement ROMs for Score and Match Golf which matched the PPU revision.

 

Fired up and played a nice game.
