From the [LTC1799 datasheet](https://www.analog.com/media/en/technical-documentation/data-sheets/LTC1799.pdf): ![image](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/4/4aa1bd27ddb5c3181f0c11ff75faa69ce7304766.png)  
I guess that the Gameboy runs at 8MHz, so you would need a 12k resistor (or 6k8 in series with a 47k pot) with the DIV pin on GND.

You can do something like that:

But you would need a floating source, or at least some weird shenanigans… Start with a vactrol.

I think your Gameboy is ok with only 5V, you can try without fry it, at least.

Sam did some clever trick for the mounting, check his video.
