/* Mug Smashers (c)199? Electronic Devices (Italy) / 3D Games (England)
driver by David Haywood - Dip Switches and Inputs by Stephane Humbert
a side scrolling beat-em-up, borrows ideas from Combatribes, including
the music (apparently) and sound hardware!
there is also a Spanish company logo in the graphic roms
a 1990 copyright can be found in the sound program so its 1990 at the
earliest

/* working notes:
68k interrupts
lev 1 : 0x64 : 0000 0100 - just rte

lev 6 : 0x78 : 0000 0102 - vblank?
lev 7 : 0x7c : 0000 0100 - just rte
to fix:
attribute bits on bg tiles - what are they for?
is scrolling / bg placement 100% correct?
dsw note:
the DSW ports are a bit odd, from reading the test mode it appears the
board has 2 physical dipswitches, however these are mapped over multiple
real addresses, obviously this gives us two ways of dealing with them,
USE_FAKE_INPUT_PORTS is used at compile time to give an option of which
behavior we use .
