Nearly 2 hours in without freezing. I've gone into the menu while jumping, being hit, and running around fruitlessly.
I've rapidly gone back and forth between menu options and between game and menu.
I've spoken to Wind after accepting a quest and not completing it.
Might be a combination of settings and an absence of a DS game.
I believe my settings are:
Safe Mode
Force R/W
Trim Rom
I hope it isn't just me, I can't think of any other difference in my setup.
[EDIT]
Oh, I use an M3 miniSD with a Sandisk 2GB miniSD card.
[EDIT2]
GAH! Looks like I spoke too soon. I froze switching from map on the top screen to status on the top screen. [SELECT]
