The very first version of the game ever made, developed by Chris Danford from May to August of 2001.

A list of features, as written by Chris on his website:

• 4 pad support! Now 4 people can play single at the same time, and 2 people can play Double on the same set of notes!
• MP3 support - no more uncompressed WAVs!
• Use any AVI or MPG video as the dancing background - even music videos!
• Full DirectInput support for PC gamepads, and PSX gamepad support with a PSX-USB converter.
• Simpler song directory structure. Everything needed to play a song goes in one directory.
• Record your own .steps files by actually dancing to the song! No more editing pages of steps in notepad.

As for progress on this build, he mentions the following:

• All graphics, sound, input, and sprite libraries are complete.
• Input mapping configuration is complete
• Menu system is complete
• Song Selection, Step Selection, and Results states are 80% complete.
• The gameplay is 100% playable, but a few of the details (dancing score, health meter) are still unimplemented.
• The 2x-double-pad and 4x-single-pad game modes are complete.
