I have an old PC game called Air Strike 3D II. I wanted to extract music files but I couldn't figure out how to unpack the .apk file (NOT Android package). 7-zip can't open it. When I open the .apk file with IDA, it says (Unknown COFF machine) and it failed to disassemble it so it's not an assembly file.
The headers always start with
0000803F 99990000. There is a folder named
sounds and it contains .wav files,
sounds/laser.wav etc... recovering files with WinHex does not help because it is packed and compressed.
I found a log file that says
---- Initializing file system ---- pak1.apk - 733 files pak2.apk - 45 files pak4.apk - 1 files F_Init: 3 data files found.
I tried to disassemble the .exe file with IDA, but there is nothing useful because it is encrypted or obfuscated.
Google doesn't give me solutions because it returns Android related results. I wish it could show results from 2008 and older.
Here are the files if you want to take a look: https://drive.google.com/open?id=0B_6TXpxCnMc7TGVfOWlYWjVYXzQ
