Suggestion: Add support for DDR X2 - DDR 2014 Games to add support DDR X2, DDR X3 VS 2ndMIX, DDR 2013, and DDR 2014

I tried using it on DDR X2 but it gives me a network busy error. It would be cool to see it run older DDR games as well. This could mean you could save scores for the older ddr games and choose and dancer.

this is similar to my suggestion for the old popn games (not mad though)
