Freezing during cutscenes/transitions, graphical breakdowns, some roms that used to work just showing up whitescreen.Define glitching?
.
I have about 75 DS games, with saves, and a GBC and NES emulator with a few roms each, BUT, it's a 16GB micro sd. So I don't THINK it could be from too much data, could it?
but yeah, I'll throw a few specific issues out and see if any of it sounds familiar. Okamiden used to work and is now just white screen. Phoenix Wright freezes in the first level (I've beaten it before.)
Same with Ghost Trick: it freezes in the first level now, but I've gotten a long way past that before.
Bowser's Inside Story has weird graphical issues during the turn based battles, and also freezes.
What's weird is that they worked perfectly for almost 2 years.
I even opened an unused R4 and micro sd and tried copying the data to THAT setup, and had the same issues.
