Research
The start of the file has a Windows PE file. O.o Not sure if just random or actually a function of the archive. From looking at the BGM file, I can find unobstructed OGG headers. The file in ever GPK file is a Microsoft.Net assembly format EXE that is only around 5KB in size. Not really sure what it does but it is the same data in every archive. Engine name might be "FORIS" or "FORIS-OS". Archive data starts at offset 0x1400.
