UltraStar is an open-source karaoke program for free.It is similar
to PlayStation2's SingStar but does not copy it. You cannot exchange
songs between both games. UltraStar is still an alpha version which
means that it is still under development and has some errors.
Nevertheless, it is a well-working program and looks nice.
This is the almost the standard version of UltraStar (0.5.2). The only change is the query for FullScreen Resolutions in SDL. The original version would crash if the return result is NULL, as there was no check.
