Dance Clone is exactly what it says it is. Its simply a DDR clone.

Changes:

added audio support and a song selection screen
arrow placement is now loaded from a different file specific to which song is played rather then being placed randomly and differently every time
there is a menu to set some simple parameters with for how arrows should be placed when generating an arrow placement file for any song that doesn’t yet have one
I rewrote everything so almost nothing is really exactly the same and I didn’t get around to reimplementing any form of home menu
