DWI was written in Visual C/C++ by SimWolf. The game has been in development since 2000 as a hobby but the project gained great momentum in July 2001. The game code was all written by hand and is not taken from any alternate source. Interesting to note: DWI supported hold-arrows for a full month before DDRMAX was officially released in arcades.
SimWolf is more obsessed with Bemani games than anyone should ever be. And for those of you who think that he coded this to avoid paying for the official games just take a look at the picture below.
This is SimWolf's desk. The man is a complete Bemaniac!
