Recently a bunch of arcade game ISOs were dumped (not linking) so I decided to datamine the majority of them. I stumbled upon Angry Birds Arcade, but a format called glcgz2 is used for the biggest data in the game files. Can someone crack em if possible? I'll send game exes if needed.

Greetings. I am part of /1CC/ and we've been snooping through the arcade dumps and done our own share of datamining, including the Angry Birds game (Runs Ubuntu 14.04.3 and has an XFCE desktop). I realized this thread is a thing so I decided to stop by.

I have noticed a trend among the file systems of some of these Play Mechanix titles regarding loose cache, logs, and library source code (some with remnant SVN cache). Can tell from library code related to glcgz2 that this is just a fancy zlib-based container.

Using the BMS utility and the script provided, I got resulting dat files. If someone can read these, some guidance would be appreciated.

Cheers.

According to leftover source code from Jurassic Park Arcade, it's possible these have texture files. Shortly after, I found out that the extracted textures are raw compressed texture files (So far I only know DXT5). Upon simple guessing, I found the width and resolution of the first texture file in pigidlesmall.glcgz2! I don't think metadata is in it however.
