I think we might want to hive off the discussion on Tournament ROMs / Home ROMs into it’s own thread soon.
But I’ll say that if people use them (and, yes, there are plenty of games which are really unusable with stock ROMs), I’d urge them to do what we do at City Champ: put a sign on the backglass (on under the playfield glass) explaining the key differences and link to the website that lists all the details.
