DBPF file format from EA's mobile games

Post by Tetriser »

EA's mobile games like the Tetris ones (the 2011 version of Tetris and the original Tetris Blitz) use this format for its .db archives.
The Dawngate BMS somehow recognized it, but it turns out that it uses a different compression algorithm.

This is how the first few bytes look, in this case, from the original Tetris Blitz:

It gave me this error:

Code: Select all

Error: the uncompressed data (-1) is bigger than the allocated buffer (212)
       It usually means that data is not compressed or uses another algorithm

Last script line before the error or that produced the error:
  31  clog "" OFFSET ZSIZE SIZE
 


Do I have to modify the script a bit or you got a better BMS script for this particular variant DBPF archive?
