Digitizing photos from the 1998 Game Boy Camera
swiftrocks.comYou can also dump GB Camera photos with GBxCart RW. Those can also be used to dump ROMs/saves and reprogram flash carts. The cheap GBC games off Ali express are flash carts in reality.
Oh yeah I forgot to mention that, it was the first option I considered but getting it shipped to Sweden was super expensive. So it didn't make sense considering I just wanted the camera dump feature. Buying the pcb and port on the other hand only costed me about 10 bucks since I already had an Arduino laying around, and also served as some necessary soldering practice :)
