Well, I've tried to "fake" the installer out with a dummy folder, since I don't have a spare game install on this computer to mess with, and I keep getting a "file missing" message, so I'm sure it's looking for something besides the SH4.exe file. Anyway, tomorrow, I'll try it on the other computer in the stock install. I'm going to say though, going by the way the author describes it, and the unconventional method of activation, that it would almost definitely not be compatible with FotRSU. I'll see if I can manage to do a merged version of it off of his TMO version, which is closest to FotRSU. There appears to be a lot though that they are changing in the mod...
