- (fixed) level 3+ boss movements looks wrong;
- stage 3 "homing" missiles doesn't seem to like our 6200 hookup here, except it's NOT 6200!?
- (fixed) barrels seen in later levels seems to fail an axis aligned bounding box, not unlike Legionnaire.
Godzilla
- few elements doesn't collide properly (i.e. Super X missiles, Tokyo's tower in stage 1),
Z axis check makes no sense whatsoever.
Kludged to work in per-game driver_init.
SD Gundam
- stage 3 mid-boss still has the sprite garbage bug;
- stage 4: has sprite stuck on bottom-left of screen;
