I am so sad right now.
We had a thunderstorm yesterday and our power went out for about 1 second (we have all electronics plugged into power surge protectors), but that was enough to mess up my Animal Crossing (which was on at the time). My unit comes on, and other games will play, but ACCF won't come on at all. It acts like it wants to load, but then I get a blue screen with Resseti on it saying there was an error and to consult my Wii owners manual. Which I did, all it says is to send the unit in for repair, they may be able to fix it, and they may be able to restore the game information. So, I might loose everything. But even if I don't, my town will be totally messed up. All my hybrids will be gone for sure.
Worst of all... I can't play. I have been playing this game and taking care of my town since January.... I had 2 fish left to catch and 4 bugs... I'm so sad...
I have never used a memory card, but I will surely look into one now. So, y'all might want to consider that too...
