Are the new files that you added those 5 folders with date from 2026?
amazoneo, teot, 240pTestSuite, 19yy and RallyChase? that's a simple test. Move them outside \games and see if it now works, but I doubt it's that. How do the games show in the menu? like 240pTe~1?
These are games that I added after doing the 2026 update
When I remove them, everything works normally, although sometimes some of the other games I choose don’t always work either (this was already happening before).
I feel like sometimes a specific combination of three games can cause one of them not to work, even though that same game might work perfectly fine when combined with three different games.
Start adding games one by one please and tell me which one gives you trouble. Those symptoms are very strange and I'd say that they are rather related to microsd somehow getting corrupted.
I just saw your message after testing the latest games that were added (not one by one), and I'm having the same problem. The menu freezes, starting with graphical glitches.
