I just do not understand why I keep seeing this. I have only seen one 'modern' hack - Dude's Mushroom Zone. Yes there are a few topics on messing with the modern games like the unused videos in Sonic Mega Collection and all the Sonic Generations resource ripping, which you really can't count as hacking if we're going by the terms of "taking a game and changing it"- people are just ripping out the innards. Everything else I see isn't modern hacking. In fact, take a look at all the topics that have been active in the past month - you'll see Sonic 2 Heroes, The S Factor, Sonic 1 Twisted, etc.
