A free and open source karaoke game inspired by the Singstar™ game available on the Playstation®. It allows up to six players to sing along with music using microphones in order to score points, depending on the pitch of the voice and the rhythm of singing.
UltraStar Deluxe was started as a modification of UltraStar. Whiteshark initially offered to collaborate with Corvus5, but this offer was declined. Instead Whiteshark started to add some features on his own with the help of Mota. The first release is known as X-Mas mod, due to a release date around Christmas time. This attracted the attention of other developers that were willing to help. The team grew and the source code departed more and more from the original. Smaller features are often implemented in both projects allowing them to benefit from one another. Though the projects' implementations of such features often differ. UltraStar Deluxe is different in three key ways from UltraStar. Significant effort has been put into improving reliability by repairing bugs. The second difference is the visual appearance. Sparkling stars and various other effects have been added in addition to skin support. Many effects are also based on the Singstar on PS3. Many new features have been implemented:
* More video formats are supported, such as DivX, XviD, FLV, Avi and WMV.
* Singing screen with golden notes, line bonus and popups
* Lua scriptable Party mode with various game types. This includes support for lua plugins that allow further extension of such game types.
* Improved song management and selection with the ability to search for songs and use playlists
* More detailed statistics screen
UltraStar Deluxe is written in Object Pascal, and compiles with Delphi, Free Pascal Compiler and Lazarus. Ports for Linux and Mac OS X are being worked on. An early and unstable version is available as a Debian binary package from their project website.
As of version 1.0.1 UltraStar Deluxe runs on Linux via Wine.
As of version 1.1 UltraStar Deluxe runs on Linux natively.
