Just get the Saturn version and treat it as an addition to the castlevania family, It's probably the worst version out of the lot but it is still a damn fine game in it's own right and the extras are a fine addition.
Oh yea. It's one of my all time favs. I used to have the Saturn version (and many many other rare titles) but my dumber younger self 10 years ago sold them all for little to nothing to feed a nasty habit I had.
Anyway, my new creamy (yellowing) Saturn came in. Works great!
yes, threw them into trash bin
