Subject: M.A.X 2 Data Extractor
Hello everyone!

Few days ago I've started experimenting with reverse engineering MAX2 asset packages, mostly as fun/learning project.

So far I've got following to work:

- isolate assets from file
- decompress and unpack images with color palettes (eg. unit portraits, logos, interface backgrounds)
- isolate TXT files
- isolate UI files no idea how to get color for those (yet!)

The code can be found here:

https://github.com/rafalp/max2-extractor

Currently I am working on correctly isolating assets of type 5, which appear to be small images used around the UI. Eg. here's the lightbulb units sometimes display. It has 10 bytes long header followed by pixel data. First 4 bytes are image dimensions, but meaning of next 6 bytes I can't fathom.

But for now I don't know how to find colors for those pixels. It appears that those assets aren't compressed and are using palette stored elsewhere:

I've got some success by reusing the palette from M.A.X1 GFX tool, but while it produces good results for some images, it completely shredded others.

I've also managed to isolate binary data of what appears to be audio files (file header appears to contain bitrate number) but no idea how to convert those to WAV. Are there any resources available on how binary data for audio looked like in M.A.X 1?
