Welcome to AP. Good to see another mtb-er on the site - I thought I was probably the only one with this overlap of interests!  I'm not a racer, but have done one 24h race in a social context.  (also great choice of games in Burger Time).  What's the preferred choice of software for diy Jukes?  I've always had a desire to build an upright horizontal format Mame, for games like NATO defence, Thief and Pepper II with a Juke box when not game playing.
