Joymax Pak File (.pk2)¶
Abstract¶
Joymax Pak File is used to store the games data files. The format is fragmented; index data and content data are stored in no specific location. Index data is stored in blocks of X entries and is encrypted using Blowfish (LINK). The content data is neither encrypted nor compressed in any way.

Data¶
Nothing special. Data is stored without protection or encryption.
Trivia¶
- Joymax’s implementation does not support defragmentation. Pak Files can only grow.
- Joymax’s implementation uses a “plain text password” instead of the plain blowfish key. The blowfish key is generated from the password.
