Kid Dracula was more or less a port of the NES version onto Game Boy so technically doesn’t count.
The only other one I can think of that you might be referring to is Castlevania Legends but they didn’t bother bundling it with this collection for whatever reason.
Well in anyone’s defense, considering the time period that game was released in, how was anyone honestly supposed to know? If you didn’t have Nintendo Power helping you and very limited internet access, of course it was very cryptic and very unnecessary.
