I have a few NES games that are in cut retail boxes (missing the top, bottom, and right side) and are then inserted into a plastic case. Not quite as good as having something CIB, but for a game like Battletoads vs Double Dragon, I'm happy to have any box at all! Anyway, my issue is that the rental boxes are ugly, the clear plastic sleeve part has started to peel and discolor. I was wondering if anyone knew of a viable replacement case to use for these mostly boxed nes games? I can add pictures later if that would make things clearer.
EDIT: Bitboxes might be an option, but I'm worried the corners are a bit too rounded
