* Fixed visible area to 288x224, fixes left-most columns (inside the big ship); * Background layers actually had reversed priority (outside and inside the big ship);

- sprite zooming;

- some video glitches;

- sound, third z80 not hooked up;

- offset sprite shrinking (ship going inside/outside the base, 2nd boss

zoom points);

- priority might be wrong in some places (title screen stars around the

galaxy, planet ship 3rd boss, 2nd boss);
