Offroad Legends XPK BMS? (IOS)

Post by squidiskool »

After many unsuccessful forums and many unsuccessful captcha attempts, I've finally came to ZenHax. I'm looking for a way to extract this data from Offroad Legends. Every other game by Dogbyte uses this weird data. Header is "XPAK". Using it with offzip just gives me odd data. Could somebody get me a BMS script or something that could help me with this data? This game isn't very well-known so there isn't any people that want to rip from this game.

The results you get with offzip are the content of the PNG files (without PNG header).
I think there is some sort of obfuscation used on the index table and on the first bytes of the archived files, but I don't have much ideas.
It's weird that sequence of 0xff bytes at offset 0x72 which makes me thing to a simple obfuscation.
