Worms 1 archive files

[Mabeas]

Worms 1 for DOS has a lot of files that are labeled pretty obviously in the data folders, but the only problem is that they're a generic "File" format. The files themselves have the common titles "COLTAB1" and "LAND1", with a few "SET" folders also including "BACK1" and "BACK2", is there anyone out there who might be familiar with these or otherwise have an idea of how I might go about decrypting them?
