clicking the link wont work, so either rightclick-save link as or copy-paste into the adresbar.
usage/syntax: MissionDecode source.ext destination.ext
usually that should be: MissionDecode missionX.dat missionXdecoded.txt
it can be used in a similar way to encode the decoded txt (or whatever) back to a valid mission file. Easy, fast, should allways work.
I wrote it in C# so you'll need the .NET framework, possibly 2.0 (not tested on 1.1)
Have fun changing missions!
