I've always found the Gameboy Camera to be an interesting and novel bit of kit. During the pandemic I picked up a GBC and camera in the hopes of diving into the world of low-fi photography... But I kept putting off modding a better battery & screen into the GBC, and most the methods out there for getting the images off of the cartridge are outdated or rather cumbersome.
Matt Walsh did a neat video about using lenses to make colour pictures with the camera - https://youtu.be/FPkJaEG-C_M
