Ok, so I can't get this to work.
I've completely cleared any installation files and started fresh and did the following based of some info from your v3 thread.
1. Convert the game using FF7 Game Converter (This creates the ff7_opengl.cfg mentioned in your v3 thread) And to to this you need a fake ISO as well. After I do this I only get sound effects in the game, but no music, any ideas?
2. Edit ff7_opengl.cfg, this a where's it's a bit confusing, should it be a full path
mod_path = E:\Spel\Steam\steamapps\common\FINAL FANTASY VII\mods\Textures
or
mod_path = Textures
3. Unpack all the IRO files and put them in the mods\Textures folder (this is also a but confusing, what should the folder structure look like here?)
