PAL Brawl suddenly stopped working

[MasterGH]

I've been using Gecko OS (1.9.2) to load my PAL version of Brawl for Brawl+ for quite a while, but this-morning it suddenly stopped working. My sister loaded it earlier in the day (to make a stage, play it, then exit) and it worked fine, but now when I go to launch it I get a DSI exception. This remains so even when I set all the Gecko options to defaults (including cheats off) and remove all my USB devices from the back of the Wii. I can type out the exception if you need it. The game runs perfectly fine in the Disc Channel still.

Just so you know, all my other games still work fine in Gecko OS, including my imported US Metroid Prime Trilogy which it allows me to play :)

EDIT: I just tried some old versions of Gecko OS to see if they'd make it work again. In fact, every single version up until 1.9.2 works! I just still don't know why 1.9.2 suddenly stopped working, because it was working happily for so long.
