Update: 12/7/2012 You can use ndstool/dslazy to dump the JUS rom. ALAR Tool handles aar archives. (Type 2 and 3, haven't seen any others) It will decompress any files in Type 2 archives by double clicking on them. (type 3 usually only contains type 2 aars and opens them natively by double clicking) You can export files as is from both types (though some files will be compressed) ALMT Parser handles ALMT move files for characters. It is command line (ALMTParser.exe "file.amt") and dumps out an xml file of the character's move data. It is currently a work in progress.
