There's a few hardware compatibility issues with the various incarnations of S246/S256.
The last system isn't that compatible either. I suppose all of the games may work if they were modified but that wouldn't be an easy job.
But yes, this is something I'd like to see in a multi-game too, even though I have most of the actual games and all of the versions of hardware

I even have a few bits and pieces that no one has..... yet
