Darkstalkers Resurrection is listed as supported format, but it only contains Night Warriors: Darkstalkers Revenge (the second game) and Vampire Savior (the third game).

I realized this after finding my PS1 copy and noticing Hsien-Ko wasn't an available character, and then looking it up.

I had a run up for this that I'm removing, but I just wanted to let you know @AquaBlake.
