mame/src/emu/video/psx.c
Aaron Giles 06da0b9b9f Change 'screen' parameter in SCREEN_UPDATE and SCREEN_EOF callbacks to a 
reference. Remove redundant machine parameter from SCREEN_EOF. Remove old 
vestiges of driver_device video_eof override since it wasn't being used.
Update all multi-screen games to use separate functions for each screen 
(calling into common code where appropriate). [Aaron Giles]

(nw: equivalent MESS changes are ready, will send along shortly)
