Same as any other vendor's version of the game. #1, you do NOT want to be in a "Program Files" directory, including as in the Steam default install of "C:\Program Files (x86) \Steam \SteamApps \common \Silent Hunter Wolves of the Pacific". You will have to have a separate Steam Library folder. I re-did my Steam installs to be "C:\Games \Steam \SteamApps \Common \Silent Hunter..." Refer to "
Moving a Steam Installation and Games" on the Steam Support site for more info on moving. You also have to use Large Address Aware (LAA), which is in the FotRSU download, as is MultiSH4, which will help with multiple copies of SH4 on the same computer. All you'll need initially is a copy of
7-Zip to extract the package in the MODS folder of your game install, and then use JSGME to activate it. Once activated, be sure and empty the Save folder (generally "C:\Users \UserName \Documents \SH4" unless you've moved it) by deleting "Data" and everything below it. Start the game, use the Options menu to set your gameplaying choices and to set your screen resolution to what Windows is set to, exit the game and then re-start it, and all of those settings should then be applied, and ready for you to do some "testing" in...
