/* 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

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 .
