/************************************************************************************** Counter Steer (c) 1985 Data East Corporation Zero Target (c) 1985 Data East Corporation Gekitsui Oh (c) 1985 Data East Corporation Emulation by Bryan McPhail, mish@tendril.co.uk Improvements by Pierpaolo Prazzoli, David Haywood, Angelo Salese todo: finish - correct roz rotation; - make cntsteer work, comms looks awkward and probably different than Zero Target; - flip screen support; - according to a side-by-side test, sound should be "darker" by some octaves, likely that a sound filter is needed; cleanup - split into driver/video; note: To boot cntsteer, set a CPU #1 breakpoint on c225 and then 'do pc=c230'.
