Good advice in general, but in this case I don't see how they'd have that option, as the long poles need to mount the display and a circuit board. See [1] and subsequently [2], and [3] which shows the rear of the GameBoy (where those screws go).I think a better solution in this case is to either just forgo wood for those particular areas, e.g. you could use plastic or metal parts that the screws would go into, and glue or otherwise securely mount those to the wood.
Or similarly, use wood for the poles, but don't drill holes in them, and use some alternate mechanism to hold the body together. They're already using magnets for the battery cover, and could presumably use a large amount of magnets to hold the two pieces of the body itself together.
Finally, I don't think looking at antique wooden electronics is going to be useful. When electronic consumer products were made out of wood the electrical components were much bigger, so they didn't need to deal with these sorts of problems. Most of those only used wood as the "box", see e.g. [4].
