Sega Dreamcast VGA Mod

Step 5 Remove the motherboard

If there are any screws at this point, remove them. You'll have a much easier time if you lift it from the front of the board, as shown in the photo. In this picture, you can see the power connector I was talking about earlier, in the upper right-hand corner of the board. Don't worry about the rubber heatsinks on those two square chips, the heat-paste will keep it adhered adequately onto the chip. If it does come off, just put it aside until you're ready to put the Dreamcast back together. The heatsink is important. Your Dreamcast won't last more than about 10 seconds without crashing if it's missing (first-hand experience).
