At the bottom of this section, where it says "Paths to search for music files:", replace the paths listed with wherever you put your music files. Make sure there aren't any spaces in these paths, or FF7Music will likely parse them wrong and not work correctly. (e.g. "C:\ff7songs\" is okay, "C:\ff7 songs" is not). If you're using Windows Vista or later, click Save and Exit and close the program for now.
7. If you don't already have it, download and install Aali's Custom Graphics Driver, and delete the # before music_plugin in the config file.
8. (This step removed, placeholder to keep the numbering consistent)
9. Right click on ff7.exe and choose properties. In the compatibility tab, set it to run in Windows 98 mode.
10. If you're using Windows XP or earlier, skip this step. Right click on FF7Music.exe and choose properties. In the compatibility tab, set it to run in Windows XP SP2 mode, and check "Run this program as an administrator".
11. Back in FF7Music.exe configuration, in the Playback Options tab, where it says "Midi device", choose the device that Final Fantasy VII is configured to use. If you're using Aali's driver, it doesn't matter what you choose.
At this point, you should be ready to go! Just make sure to launch the game from FF7Music.exe instead of from your regular start menu shortcut or from ff7.exe.
