Why not use Swp.exe... anyway...
There might be a way and you just need to try this as its totally untested.
Download the following zipped files:
http://www.proasm.com/files/sw/rwdbox.zip (8 megs)
First unzip all those files into some folder (not sw)
Then rename the .map files exactly as follows:
rwdream.map rename to $whirl.map
rwtown.map rename to $tank.map
rwjail.map rename to $boat.map
rwboat.map rename to $garden.map
rwfarm.map rename to $outpost.map
rwfinal.map rename to $hidtemp.map
Now copy all the files including the renamed ones (176) directly into your SW folder.
Start sw and play the second episode (Code of Honor)
Rampage Warrior should start - no guarentees
To remove them again when you finished just list your folder in date order as all these files are dated 29th March 1999
