Excellent news! Glad you are going. Most mods are done the same way. If you go to change mods in the future though, remember to empty your Save folder ("C:\Users \UserName \Documents \SH4") after you change the MODS configuration. One option for that is to use multiple copies of the SH4 game, each in a unique folder, and then point the SH4 FileManager.dll at a different Save folder for each copy with the use of
MultiSH4 - no need to jump into the deep end of the pool just yet though. Get used to what you have, and when you get curious, give a shout and someone can get you set-up with another copy of SH4 on your computer.
