Well Hello!! Glad to hear your affection for this wonderful system, but where have you been?? Just kidding.
As a Turbo owner since '89, I can answer your questions. First of all, you can't save games on the system, just passwords if the game supports them. Super cd's require a super system card, also known as the 3.0 card. When you get your cd add on, you should have a 2.0 card with it. If you don't, your not playing any cd's with it. The super cd's need this more powerful card to play on the regular cd system, otherwise, you'll have to have a Duo. As far as Dracula X, you'll need some luck, and quite a bit of money to get your hands on one. You can always keep an eye on e-bay, but I've seen them sell for over $200. I'm just glad I imported mine years ago. It will play on your system no problem, and you can always settle for a copy of it, instead of an original. That game is worth having in any form I think.
