Haven't got around to playing this one again, but many years ago I had managed to beat the game with the secret True Lance Knight fight. I did fumble the fight and I was playing in one-round mode...but hey, at least I can keep track of that here. Will update this if I actually bother in playing this again with two rounds today, whether I just do a normal playthrough or if I actually manage to go for TLK again.

Very underrated and solid fighter. The soundtrack is amazing.
