I've just updated to firmware 1.13.1 which gives a proper error message on the crash screen (typed by hand):
Run loop stalled for more than 10 seconds
pc=0x08093034 lr=0x00000060
[C] drawFaded()
wipe.lua:57
Oooh interesting. I'll move the game to the latest SDK and try to get an update out tonight.Truly appreciate your patience and help with troubleshooting.
