I post this so you don't waste your time.
Apparently if you have a SuperCard DStwo, your fine. I started my adventure on a SuperCard DSone (Sp5 08-21-10 most recent update), and after the intro, after talking to a couple people, I searched the nearby surroundings, and then it crashed to black screens.
I copied my save file to my R4 card, sporting the recent 1.12 Wood firmware, and I managed to play about 5 more minutes until the next crash. As much as I love Hotel Dusk, and as much as I want to continue this game, it's impossible. I've never played Pokemon, and can only hope that the fix for this game comes sooner than later. When given the opportunity, I will buy this at retail, since I already know how great this game is. Until then, don't bother downloading this game from your Spanish-speaking site, or virus encrusted torrent search engine.
A firmware update is required, simply put. I only wonder why Nintendo doesn't invest in the same AP protection as this game. Baffled, I am.
