[bug#57861] [PATCH] gnu: Add ultrastar-deluxe.

[Lars-Dominik Braun]

Hi,

this patch adds UltraStar Deluxe (USDX), a karaoke game. The top-level
directory includes a copy of the GPL and the game sources also bear GPL
headers, but there is no explicit license for assets, so it’s hard to
tell whether they are actually free or not. Any opinions?
If not, we could move this to the Guix games channel.

Cheers,
Lars
