I have a 3.2u wii with a backup copy of animal crossing city folk. I seem to get a little board with the usual "fun" gameplay but I want more.... So i did some googling and came up with ACToolkit. it edits your savefile to hack your map and so on. I backed up my animal crossing save file and as always, it is a .bin format. the program asks for a .dat file extension . what do I do? do I need to convert something or am I using the wrong file. please help!!! thanks.
