It's working great. Thanks!

Thanks to both of you for taking a look!

aluigi, if you could post a QuickBMS script or something to break the encryption, I could try to work out the format myself (I've successfully done it for a few other archives). If I had trouble with that, I could come back here again

Thanks again.

Hello again, I was able to extract some data from the .fun files using offzip. Unfortunately, I'm still unable to figure out the rest of the archive which would seemingly contain the filenames, etc. I was looking at Delta Force: Razor Unit (a game that uses the same packfile format, or very similar)...

(Not sure if this should go in the "Compressed files and methods" board or here) Hey all! There's this old game called Secret Service: In Harm's Way and it's got a file format that I haven't been able to extract :(. The extension is .fun, presumably a custom format by the game's developers...
