I was poking at the data of "A Reckless Disregard for Gravity" and found two files, audio_metadata.dat and audio_resource.dat. The former is human readable, pairs of integers delimited by \r\n. They look like pairs of offset and length in bytes, with audio_resource.dat holding the audio data. The length fits perfectly, so I'd say that hunch was correct. However, I'm not sure what data is in audio_resource.dat exactly. When splitting the data using the metadata, I end up with a bunch of files with two different headers total (or so it seems, I haven't checked them all). The first's first four bytes are AD B6 B9 B9, and the second's first four bytes are B0 98 98 AC. The files aren't recognized by Audacity or ffprobe, so I'm not exactly sure what I am dealing with here. Are they compressed? Encrypted? According to PC Gaming Wiki, the game was created using Gamestudio A7, but I couldn't find any details on audio for that program.
Has anybody seen this before, or does anybody have any ideas?
