Most Genesis games came in really useful hard cases that held everything and made keeping games sorted out an easy task. None of the Nintendo cartridge systems had games that came in these kind of cases, but did any third parties make Genesis-style hard cases for NES,SNES or N64 games?
I've seen plenty of rental-style hard cases but those don't have the see-through boxart sleeve around the outside that Genesis cases did. Did/does anyone make them? Would there be any good substitutes?
