Ha! You all probably thought I forgot about this! Well, I didn't!
That being said, I just completed a game as requested by Duke.Togo, Ninja Ryuukenden! And Duke, you better be happy that I beat it, because it was hard. Very hard. Still, it was easier than The Adventures of Bayou Billy, if that means anything.
Done so far:
The Kung-Fu Majin Eiyu Wataru Splatterhouse Street Fighter 2 CE The Tower of Druaga Ninja Ryuukenden
