Much thanks for your reply! But just in case allow me to get the details...
So I downloaded the FourPlay mod which is a pak, and it doesn't even require a folder. All I had to do was drop the pak into Data folder. In this case, all I still need to do is just follow your instructions to the letter, and not touch the pak itslef, or do I need to move the pak itself into the newly created folder?
Since you said the mod will not work with old save files, there isn't any way to see if the resist caps are working properly right out of the box is there?
