Apart from buying any cheat games, theres nothing really you can do except from saving up money and selling rare items. The best advise I can give you is to reset your clock to the Flea Market, and sell rare items and get alot of money for it. I hoped this helped!
With hacking-action replay
No sorry
No.
No, you cannot. You can with an Action Replay code, however.
Action Replay.
It wont always work because action replays dont work on some games but you insert the action replay then (without turning of the power) insert animal crossing, then click on the little star in the corner and animal crossing codes will come up , tick the ones you want, then it will say insert action replay so do that, it will say saving changes, then you insert animal crossing again and animal crossing will come straight on and you should have your cheats working. BUT! It wont always work, on my action replay, i do all that on some of my other games and it works but my animal crossing just freezes when you choose who you want to play as so i get no cheats :(
You can't remove them from Animal Crossing: Wild World without an Action Replay.
No, the 1-bell mortgage code only works when the Action Replay is in and the code is on.
There isn't an action reply code to see a UFO on animal crossing because you can without it, (on animal crossing Wild World and City Folk). On a random day, a UFO will float above your town. You shoot it down with a slingshot, and that is how you get a UFO in your town. There are no AR codes needed.
