/*
- sound CPU seems to miss commands sometimes
- flipscreen is wrong
- should sprites be buffered (is there a Deco71?)
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;
- Clean-up the whole routine;
-- Dip locations verified with Japanese manual
