/*************************************************************************** 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.
