+
+ Super Burger Time (c) 1990 Data East Corporation (DE-0343)
+ China Town (c) 1991 Data East Corporation (DE-0343)
+
+ Sound: Ym2151, Oki adpcm - NOTE! The sound program writes to the address
+of a YM2203 and a 2nd Oki chip but the board does _not_ have them. The sound
+program is simply the 'generic' Data East sound program unmodified for this cut
+down hardware (it doesn't write any good sound data btw, mostly zeros).
+
+ Super Burgertime has a few bugs:
+
+ Some sprites clip at the edges of the screen.
+ Some burgers (from crushing an enemy) appear with wrong colour.
+ Colour cycle on title screen doesn't work first time around.
+
+ These are NOT driver bugs! They all exist in the original game.
+
+ Emulation by Bryan McPhail, mish@tendril.co.uk
