Well, after a disastrous week of trying to get Hyper Patcher 2, AutoFontInstaller and all other manner of Font modification done to this program... I've thrown in the towel after having to spend an entire day trying to force a system restore to repair the now borked game (kept crashing with some Direct Draw error upon loading the game full screen).
We'll just have to live with one of the default fonts. The second one doesn't look too bad.
