Dowload moslo. ( I think it's moslo132.zip or moslo.zip )
Unpack it with winzip, winace, winrar or the build in zip program in xp.
To run the program:
in the start menu, select Run... , then type cmd, click ok.
Change the path to the moslo path. Something like that:
c:
cd\games\moslo
Now, run the game. The /20 parameter is the percent of the slow down. You can change it, if it's too slow or too fast.
You can change the game path too, if it's not the same.
moslo /20 c:\games\wc1\wc.exe
