/* Not so lame actually, but I keep the original comment (funny).
   This comment from Antiriad was probably out of frustration since he was trying
   to emulate a 65ce02 without knowing it was a 65ce02 and his cpu emulator didn't
   support it !

   So I used this driver to first upgrade our 6502 emulator to support the 65ce02
   and since the seta games were not bad at all after all, I added a few pure 68k
   games too. As often in these times, big thanks go to the mame devs for their source
   code which was an unvaluable source of information !

   About the pure 68k games : this driver shows a few tricks to make them to work,
   from the weird palette mappings, to the weird use of interrupts (rezon).
   There are also a few oddities in the way roms are loaded/decoded sometimes.

   I like this driver a lot in fact, some of the games are as good as the cave games
   without all their stupid sprite size changes !

   TODO : some games use dipswitches on 16 bits. We can't handle them for now.
          Maybe I can find a trick to handle this differently, or extend the dipswitches
	  to allow 16 bits entries...
	  For now it's handled by adding the "alt license" dip switch on the 2nd byte
	  This "feature" is used only by the games reading their dsw with a 6502, I think
	  this "alt license" dsw is more than enough to handle it.
*/

/* Use the xsystem1 video engine to draw the sprites ?
   You'd better leave this commented : for one thing this engine starts by clearing
   the screen, it's not supposed to work with layers.
   For another, it does not support sprites banks and finally it adapts very badly
   to borders != 32 (it can be adapted but the code is really old and used by quite lots
   of games, so I prefer to handle the sprites here, locally)
   Maybe the 2 versions should be merged, but only once I am sure the one in this driver
   is perfect !
