I could have beaten Dracula's Curse, but my nintendo cartridge kept frezing up after I beat the Gargoyle boss. Or rather, the Orb didn't load, so my time ran out and I die >.>
I'm on my way to beat the original Rondo of Blood. So I'm missing quite a bit here.
Chronicles, I didn't like so I never finished however.
