mame/src/mame/drivers/dblewing.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)

/* Double Wing */
/*
the most protected of the DE102 games?
Protection TODO:
- 3rd Boss (with Red Plane) causes a crash to the main CPU if you don't beat him on time;
- What is the $330 related for? Appears to be read when you collect a power-up.
- Check the remaining unmapped read/writes effect;
- Boss BGM might be wrong / variable;
- Haven't yet checked if bonus life and difficulty DIP-SW are rightly tested;
- Demo Sounds DIP-SW doesn't work?
- Clean-up the whole routine;
-- Dip locations verified with Japanese manual
