Hey there! I'm looking for a way to get the graphics from the game Alien Nations. There are in a few archives with .gd extension.
I would like to use the graphics in an article on TCRF and upload them to The Spriters Resource.

I have little to no experience with reverse engineering files, so I'm asking for help here. I hope you can do it.

Here are a few examples:

Ok, it unpacks the archive, which is great, don't get me wrong, but do you think you could convert these files into a common format?
Should I make a new topic for this in Graphic file formats?

The information about each file consist of 64 bytes of which only 4 are used for the offset and the rest are probably related to graphics information, for example this is the entry of the first file in Addon.gd:

Code:

0c 00 00 00 00 00 00 00 00 00 00 00 34 00 00 00   ............4...
54 00 00 00 02 00 00 00 40 01 00 00 d5 00 00 00   T.......@.......
40 01 00 00 f0 00 00 00 ce 00 00 00 d4 00 00 00   @...............
0a 00 00 00 04 00 04 00 00 00 00 00 00 00 00 00   ................

I don't know if they are useful or not, anyway it's better to move this whole thread in the Graphics section if for you is ok.
