I have a few Super Famicom Tetris games, and I was wondering if these cases would fit them: http://bit.ly/1gwvzYs I'm currently editing a Tetris 2 insert I got from the Cover Project site, so that it's for a Tetris Flash case, but it's a useless image file if I can't put the game in the case.
You could ask the seller if it fits a Super Famicom cart - that's the only way you'll get a definitive answer.
That's really just an ordinary Universal Game Case. Super Fami games do fit but they'll be just a little bit loose.
