    Note that on some Dreamcasts the power board (on the left) overhangs slightly over the controller board, meaning one must also remove the power board at this stage. This is relatively straightforward, fortunately. Remove a screw each at the top left of the power board and at the bottom left of the power board, remove the white clip at the top left, pop out the white clip on the left of the power board and lift the power board out from the front where you have the white block containing eight pins that connect the power board to the sub board. Then proceed per the rest of this guide. Hope this helps.
