Sorry for asking such basic questions, but my knowledge about this is pretty low and I just discovered this harmony thing yesterday. After you purchase it, where do you find/how do you get games to put on it? Is there some place online where there's a list of almost every 2600 game ever created and you can just choose which ones to download? How do you download them? Do you have to pay for the files? Does this mean that all my hundred something 2600 cartridges are basically pointless to have now (other than being cool to have as a collector's item)?
