I could be wrong. However I think the latest genesis everdrive is 100% comparable for all SMS, Genesis, and 32X games. Provided you have the attachment for the 32X. I don't think you need the SMSM converter as it's just a pass through to allow the carts to interface with the genesis hardware.
I don't know about the SMS, but all 32X games work on an everdrive.
I was bored one night and the library was small so I decided to see if I overlooked anything. Long story short, I was left with one question: why the hell is Spiderman Web of Fire so expensive!?!? ...people are stupid.
Basically one of the last games manufactured for the system, and it's not a sports game. Personally I think World Series Baseball 32X is more uncommon, but it's a sports game so people overlook it for... SPIDAMANG!
