A few months ago I got a Famicom Disk System and have started getting games for it and one of them is just the disk, no box or jewel case. I was looking around and noticed that replacement disk cases aren't really a thing. I understand it's pretty niche, but still I'm kind of surprised no one has made replacement cases for Famicom Disk games. The closest thing I've seen is someone using a DS game case which seems to be the solution for all loose games. Got a loose Game Boy or Game Gear game? Just shove that thing into a DS case and print out a cover. While that would certainly work, I feel that it'd look pretty stupid on the shelf next to the other FDS games that are in their actual official case. I know the disks that Nintendo went with are based off of Mitsumi's Quick Disk but replacement cases for those don't really seems to exist either, so the idea of using a Zip Disk case came to mind. Zip Disks are a little bit larger than a Famicom Disk, so one should fit in a Zip Disk case no problem...other than rattling around a bit, but I'm sure that could be fixed somehow. Plus I feel like it'd look a bit more aesthetically pleasing on a shelf that a random DS case mixed with a handful of cute little disk games. I haven't tried this yet, but I thought I'd see if anyone else has loose FDS games and what they do with them to keep protected from dust and whatnot. Currently my loose disk in kept in a protective resealable bag made for Game Boy manuals and it fits quite nicely in there.
