I have had my cousin’s blue Game Boy Camera for years and the save file has been corrupted like super long ago. Most of the pictures are copies of the first one, and none of them can be deleted, they just pop back up after the animation.
I exctracted it, and read it with an old software from 1998 and… the overwritten pictures are all there. Memories from my cousins. Some people I don’t know.
I can share 4 those pics though.
The problem is really just the save file. I erased it and also flashed it with a save file from a working unit and it works fine. And the broken save file behaves the same on the known good unit and in an emulator. I loaded it in a hex editor and it looks kinda garbled, it’s weird.
Since the lens on that old game boy camera is scuffed and you can’t take pictures with it anymore, I’ll swap the working lens from the other unit I have (since it’s less sentimental as I got it later) and salvage the remaining parts to get this mod: https://www.youtube.com/watch?v=EccVHo-pDGI
