I've thought about that too. For the time being, having just the major releases and the most proficient sim authors would be fine. Keeping a record of all the variations of a sim file, let alone finding all of its instances, is a ridiculously meticulous and time consuming work - and i wasn't thinking about that either, i personally don't care too much about dumpy unplayable charts from forever ago just for the sake of history. I prefer to have a simfile database with the best stuff available for players who care about playing more than collecting :P
