Note that the header size doesn't seem to be in the header like the above script assumes, seems to be just 0xC0 from the files I came across so far.

In which games does it appear?
I haven't seen any files with magic “HIG!” yet.

It reminds me a lot of LZ0, but it has different code blocks.
It should be easy to implement.

I encountered it in Ratchet & Clank: Size Matters, the .wad files

I can also make a compressor, but unfortunately there seem to be several versions that are not well documented.
Do you happen to know anything about its metadata?

[smiRaphi]

I sadly do not but you could try contacting this person here https://reshax.com/topic/18804-psp-ratchet-clank-size-matters-wad-hig/?&_rid=15412#findComment-102939
as he was able to make a decompressor on his own by looking at the game executable

I'll start and see what happens, I'm just wondering if there are more than two versions.
I read that Ratchet & Clank: Size Matters is version 6.

There seems to be a footer at the end of each file, probably build information.

I would first add these versions in a minimal form and expand them if more information becomes available later.

I think the footer is specific to that .gim file, I made a kinda messy extractor for the decompressed WADs: https://github.com/smiRaphi/UniPyX/blob/5e7aa008bcce106fe22f8d836a3bdfc5b941edf9/lib/sub4_2.py#L873

This should now work for all files in versions 5 and 6.
Ratchet and Clank: Size Matters PS2 is version 5 and the PSP version is version 6.
