I've been having problems with my Nintendo 3DS XL for several days now. It all started about two weeks ago when, suddenly, without me having done anything or changed anything on the console, it stopped loading 3DS games. The strange thing is that Nintendo DS games still work normally, so I've been able to keep playing, but only those types of games.
What's most confusing about the situation is that the custom theme still displays correctly, which indicates that the console does detect the microSD card, but the 3DS games still won't start. Since then, I've tried several solutions on my own, such as restarting and formatting the microSD card, changing the adapter, and even checking the files, but nothing has worked so far.
Because of this problem, I've spent the last two weeks playing only DS games, as that's the only thing the console allows me to play without errors. The situation is quite frustrating, especially considering that I bought this 3DS XL at Christmas and until recently it worked perfectly, without any problems whatsoever.
I would appreciate any help or suggestions to solve this problem and be able to use the console normally again.
