I picked it up recently for $19 (trust me when I say that's decent value in Australia). I've only given it a brief look so far, and it looks fantastic, but I haven't given it a full playthrough just yet. I played on the 64 a bunch as a kid, so I'm plenty familiar with the game.
How about Castlevania 3: Dracula's Curse? If you haven't played it, I recommend getting it on the eShop. For me it was the best game on the NES and still holds up remarkably well today.
