Does anyone here have experience with Game Extractor?

Anyway, sorry for crashing out on you.

Have no worries! I enjoy challenges very much ;-)

I'm pretty sure the MIDI is a sound test file

Yeah, could be. Very likely even.

I'm pretty sure I know which files are the character sprites and building/map sprites, but they are impossible to crack into unless someone has the game's libraries figured out.

I've tried to identify all. I've attached a full list with their detected formats.
- TSFO: probably file offsets, not a real file, just archive internal data
- DICR: no clue, dictionary or directory indices maybe? Probably archive internal data
- CSER: these chunks store the actual file data. Format: 4 bytes CSER magic, 4 bytes length (including header), 16 bytes unknown, rest file content (so you need to cut off the first 24 bytes to get the actual file data)
- TILE: no clue, probably custom image format for map tiles
- AKOS: no clue, but looks like some sort of image files
- ALSV7195 / ALSV7020: some sort of scenario or map files maybe?
- MS Windows cursor resource (.ico)
- PC bitmap, Windows 3.x format (.bmp)
- iMUS audio file (use GR)
- ASCII text (use Notepad)
- FLI / FLC animation (you can play these with VLC for example)

For the unknown formats I've added the hexdump of the first 32 bytes. There are 1221 files in total, 90 are unidentified.

EDIT: here's a little tool to help you. Usage: just drag'n'drop the archive (like ALIFE.000 or MEDIUM.000) on extract000.exe and it will create a directory with ".extracted" extension (like "ALIFE.000.extracted") and will extract all files into that directory, but unlike Game extractor, this will properly cut off the chunk prefixes, so it just saves the actual file data. Hope this is going to be useful to you! (Known issues: it will only work with DOS file names, so use a preferably short path with English letters only.)
