Fairy Tail (魔導少年:力量覺醒) mobile game encrypted/compressed ?

Post by condemn »

Hey guys,

I've been looking at this chinese game but it seems the files are encrypted/compressed ?

The png images aren't opening and the Spine2D files (.atlas, .json and pvr.ccz) neither. The Spine texture uses TexturePacker's compression (ccz) which I read uses zlib compression.

I've tested different bms scripts but no luck of course.

Anyone has an idea or experience with it ? Here's some samples attached below. Thank you !

Most of the files if not all (png, jpg, atlas, pvr.ccz, json) start with the same 4 bytes FE FE FE FE.
