Thanks to kiriri, I got the nodvd patch. Now to install, I assumed I had to copy the contents of the mounted disc folder elsewhere and proceed (since I can't put the nodvd patch in that folder). So I did this and renamed the patch to BGI, started the installer and it installed seemingly just fine and the setup screen now has the option to start the game at the top. But when I go to the folder where I installed the game and try to open the nodvd patch .exe file, I get an error saying it couldn't open the file and the location of the folder with \BGI.exe at the end. Putting the original BGI file there and opening it doesn't do anything either.
