It's not in the filesystem, you should be able to find it in the menus somewhere or by right clicking on the main partition. I don't know what software you're using.
[edit] Never mind, arbin got it for me.

[edit] Located decompression at 801666F0, should just be a matter of time now, we'll see how much time I get to study it.
The compression algorithm used for the .res files in this game is QuickLZ 1.2.0 developed by Lasse Mikkel Reinhold.

I have more detailed file specifications for .res and .toc files if you guys want them.
I've successfully been able to extract most files from the archives, but I don't know how to reverse engineer the sound effect audio files (specifically the files in racesnd.res). It appears you guys have had some success in the past?
Some help on this would be appreciated. The best way to get ahold of me is on the Excitebots Discord server, but I will also check this thread periodically.
