About This File
Tools to decrypt any file from Idolmaster Platinum stars / Stella stage games
Usage:
1. decrypt header with twister.exe
example:
twister.exe chr_face_mik.jxk
This will create a new file with additional .dec extension, in this example: chr_face_mik.jxk.dec
2. decrypt and unpack file body with IdolMasterDec.exe
example:
IdolMasterDec.exe chr_face_mik.jxk.dec
This will overwrite original chr_face_mik.jxk file with fully decrypted and unpacked file.
You can use both tools with batch to decrypt all game files at once.
