As far as I can tell there is very little information on most game files. In particular, I couldn't find anything regarding .pow files at all.
From what I can tell, it has some string fields, and the values are stored in some weird mixed format that contains the value in text format (e.g. "0.0125" string), then as a 4 byte float, and something else. In some cases its even worse, possibly lua bytecode (since the files start with "0000.lua")?
Has anyone done any reseach on those?
