It's only been confirmed to affect few games (persona Q and pokemon moon) because some 3DS game cartridges were manufactured cheaply and are more prone to degradation then others.
Interesting. I heard a rumor a while ago that the same would happen to the WiiU console if you didn't fire it up for a long time. No idea it also happened to cartridge games. I guess I'd better go through them all soon.


. I have a modded N3DS, but very outdated. I should probably look at some of the newer methods. I remember the old non-perm method from way back when and wish the Switch found a perm solution!
