All right, so I got Twilight Menu to boot again, but only after uninstalling the CIA and removing a couple of games from my DS folder. However, after reinstalling Twilight Menu and adding the two games again, my 3DS won't boot up, even though the power light is on.
So yesterday, I was using Twilight Menu just fine, and added a couple of more games onto my 64 Gb SD card. After that, every time I try to launch Twilight Menu, it never boots, and hangs the 3DS. Anyone else having this issue?
That's what I did. I created the partition, and then tried to format it with GUIFormat using 64kb, but it told me that the partition size was too large
