The Game Boy modding scene is fascinating. You can literally replace every single part of it other than the `DMG-CPU` main SoC.

Well even that can be replaced, sorta: https://www.youtube.com/watch?v=EccVHo-pDGI

There's a replacement motherboard which uses an FPGA in lieu of an original GB/GBC/SGB SoC, so you can in fact build a Gameboy of Theseus with zero Nintendo parts.

You can also get an FPGBC which is FPGA of a GBC. They even sell them prebuilt for $99. So all parts are 100% brand new.
