# todo: 
#
# * both shooter and skater try to load a demo.dat from /usr/bin.  hack them to
# use usr/share subdirs?
#
# * similar problem with setup?
#
# * setup and shoot seem to need 8bpp video modes.  can we hack them for
#   32bpp?  Would it help to use a differnt video driver than just 'fbcon'?
