A utility for extracting and repacking the contents of DMF files
Typically these files are with the extension .DAT or .DMF
Capable of 1:1 File extraction and repacking
This tool was designed specifically for .dat files found in the 涼宮ハルヒの逆転 fan game (Suzumiya Haruhi Ace Attourney Fan Game) from the early 2000s
