That's where the item randomizer for Castlevania: Aria of Sorrow comes in.
The Castlevania series in general has a long list of games and many of them can easily be enriched with even a simple randomizer. It's not just NES and SNES games (although those do tend to get a lot of focus as they're classic games that have been around forever and are prime for reinvention) but later consoles' games as well.
It does seem like every game at this point is going to have a randomizer made for it eventually.
