Ah, well. Still never beat it.

There's a PC version of the game. The Odie Dracula level is Level 3 in that version. It was Level 1 in the Genesis version. Not sure about the Game Gear version. Plus, the PC version had a Sci-Fi level.

How to defeat Odie Dracula (because I'm in a good mood): This is easy. Just wait untill Odie gets in one of the coffins, then jump on top of the one he got in, then jump up. You'll then open the window curtain. When Odie comes out, he'll get hurt by the sunlight. Repeat two more times.
