This game was introduced by Corvus5 who has written most of the code by himself.
Basing on the official release 0.5.0 Mota and Whiteshark started to write little
patches and modifications, and released this package named ultra-star.dl.am Mod.
This modification was continued at Sourceforge.net by the Ultrastar Deluxe Team:
