Windows 10 can cause you issues with modding if you installed the game in the "Program Files (x86)" folder. Your Windows UAC (User Access Control) and Windows newer "protections" will 'save' you from yourself and prevent altering of most anything in the Programs folders (I say this facetiously, but seriously), . If that's where you have the game installed, un-install it, and delete the "My Doccuments / SH4" folder, which holds your settings and gameplay stuff. I would recommend that you download and read all that you can about
Rockin Robbins SH4CMS utility, especially if you plan on trying other mods. You don't need to get all familiar with MultiSH just yet, but you might like what it can do also. Another thing, when you go to do the mod installations, pay particular attention to the folder structure of them. When you "install"
JSGME (read the ReadMe stuff), it makes a MODS folder for you in your game folder. The mods go in that folder, but they have to be "built" like "ModName / Data" and all the other folders in that. Mods like FotRSU will have a "Support" folder also, just below that "ModName" folder, and a couple of Keyboard picture files in the "Root" folder of the mod.
