Nintendo Vs. System Part 1 The MDS Board

Arcade Laboratory 19 min Published Jan 2025

About this video

Nintendo Vs. boards are toured area by area in the opening of a repair series, from RAM and ROM to CPU, PPU, video, audio and control circuits, to help narrow down faults.

Good to know: First part of a series; it explains the board and does not repair it.

Why watch it

Start here before any later instalment, since it maps the board and repairs nothing. Side 1 and Side 2 RAM get separate attention, along with ROMs and the PPU.
