Gah, I edited the .bat file and change the folder's name to ResidentEvil (and I copied+pasted the name to eliminate the chance of any spelling errors), and it does the same thing.
I remember I had a mod program from the old forums that was very handy. I can't remember what it was called or who made it, though. It listed the folders in the C:\Soldat\Mods directory and let you select one. It then ran the selected mod. After I got a new computer, I lost it.
EDIT:Oh, and the 'play MS' button on Mecha Soldat does the same thing, so I'm sure it's not me...
