Note: if MAME_DEBUG is defined, pressing Z or X with:
Q,W,E shows scroll 0,1,2
R,T shows road 0,1
A,S,D,F shows sprites with priority 0,1,2,3
X shows some info on each sprite
M disables sprites zooming
U toggles the display of some hardware registers'
values ($80000/2/4/6)
Keys can be used together!
Additionally, layers can be disabled, writing to $82400
(fake video register):
---- ---- --54 ---- Enable Road 1,0

Each of the 256 (not all visible) lines of the screen
can display any of the lines of gfx in ROM, which are
larger than the screen and can therefore be scrolled
