SO I've been working on hacking my Wii so that I can extract an Animal Crossing save file. I was then planning on writing a program in C# to modify the values that affect stored patterns. Well I've finally got the save file extracted. As I suspected however, the save files are stored in .bin, .sgmgx, .dat, and .vff. and are otherwise unreadable. I was curious whether there was any possible way to make these files readable, or at the least, modifiable. I'm going to continue researching this but, I feel like this community knows more about this kinda thing than anyone else would. I know that an AC Toolkit was made for Animal Crossing and can be used to modify everything from how much money you have to the appearance of the character, but I'm not sure of what is going on behind the scenes. If anyone can help I'd be very grateful!
