Here ya go. This one's relatively medium-sized, some are only a few megabytes while others are in the 200-300 range.. I have no idea which contains what though.
Well, I've tried everything I could think of and unfortunately I can't get anything.
Ah well, didn't expect much anyway. I've been reading up on bytes and the format looks fairly simple, so hopefully I should be able to extract something soon enough.
Well I haven't been able to extract anything yet, but I've successfully managed to read the header and other information (e.g. I can see how many files of which type there are). So at this point I'm pretty sure I should be able to extract files as well as anybody who knows C++.
So yeah, I guess this request can be marked as completed. If anybody wants to contact me about this for whatever reason feel free to send me a PM.
