Sorry if this has been covered elsewhere but I am clearly thick - I can't get the trigger to work in Ninja Assault so just get killed by the first two guys and that's as far as I can get.
I figured out how to calibrate the guns etc in the other light gun games and they're perfectly playable but was wondering if there was an issue with this game or something? There's an entry in the changelist which says "NAOMI: Ninja Assault light gun fix" which makes me wonder if it works differently from the other light gun games... and if there's something obvious I've missed or I'm not doing right here?!?
