Changing the original Steam name of the folder would get you another downloaded copy... never thought of that... ~lightbulb~!

But no, you do not want to be saving several version of the game all to the same Save file. It will cross-contaminate the installs. You'll end up with a mess, and then CTDs. If you run the MultiSH4 file, and the dll can't be written, you should first make sure that the files are not write-protected. At a minimum, the SH4.exe and the filemanager.dll, so that changes can be made to them. Also, sometimes it won't take because the SH4.exe has been altered by LAA, so do that after the MultiSH4.

You do not want to defeat the Steam licensing. That's why you put the games on the Steam menu, then they'll run fine, one copy or ten...
