I placed my bells in the bank, saved, powered down, took out the cartridge, set the year to 2099, checked my game, and nothing happened. I didn't gain ANY interest.What went wrong?
change the clock on your ds before playing animal crossing, you may not wanna do it though because weeds are everywhere i did it!
You need to turn the ds off, remove the cartridge, turn it back on, change the clock on the ds, turn it off, put the cartridge in, and turn it on. then play the game
For some reason, going all the way to 2099 doesn't work. You can go by month or year. Put your bells in the bank, save, power down, turn on, go to DS settings, go to New Year's eve, save, power down, turn on, select Animal Crossing: Wild World, select character, check mailbox, repeat. That should work. It seems like you only gain interest if it's on New Year's eve. There HAVE to be fireworks going off. If there aren't, the clock isn't set right. Hope this helped! ??
