I wouldn't mind one that gives you a million Ritch...just for a nice head start. That's hardly enough to buy everything in the game....but enough so I don't have to fish/bug hunt/mushroom hunt/treasure hunt every single day just to turn a profit...lol.

@Lupin: The maximum's 999999, if I recall correctly. Though you don't even need an Action Replay code to get that much.
Do you know about the bank trick in Animal Crossing? Deposit some money in the bank, skip ahead by 20 or so years(99 if you really want to be safe, though have fun pulling all the weeds after that...), load up the game, save, set the time back to normal, load up the game and check the bank.
The trick works here too, from what I've heard, though you get less money since the maximum limit is lower.
