If you want to make them work with 7th heaven you'll need to make a folder with 4 forders inside them named
"char" "battle" "world_us" and "Preview" and then paste the files from each folder into the same folder. ot the folders themselves but the files inside said folders.
Open notepad and paste this inside:
Then save this notepad inside your new mod folder and name it "mod.xml"
You can make these things whatever you like. Put your own name blah blah.
If you want the mod to have a picture then add a picture named "Berserker" as a PNG file into the "Preview" folder.
Open 7th heaven and click workshop/pack and unpack to IRO
Choose pack to IRO and target the folder with these inside.
Then for the IRO name it Models or The Berserker and put it inside
"FF7 Directory/mods/7th Heaven"
After that depending on if you have "Auto import new mods" ticked in 7th heaven it will work.
If not then go to your "Library tab" and click "Import" and choose your new IRO.
As for the Direct mode, it should have been as simple as place all the files from inside each folder into the corresponding folder. Open the "Opengl.cfg" scroll down to near the bottom and change "Direct_mode = on"
That should be it....
Either way if you do this the 7th heaven way loading time will increase tenfold but only when you click play. Game loading time is normal.
