animalcrossing toolkit need help

:(I open ac toolkit and search for my save data (which saved properly) and opened it up to RVFOREST ,next i was told to use actoolkit to open RVFOREST but a popup said invalid file... it is a .DAT file
-thanks for any suggestions or help

ps. i started a new town without doing nooks chores or anything exept for buying a house and talking to a few people

Maybe this will help:: http://www.wiisave.com/?cid=218

If i remember correctly it should be a .duc file...

.duc is the format of save files extracted by the DS action replay.

cloudco:
Did you extract the file via Waninkoko's savegame manager or savegame extractor? Feel free to upload and link to the save file; I will take a look at it.
