/*
DJ Boy (c)1989 Kanako
Hardware has many similarities to Airbusters.
Self Test has two parts:
1) color test : press button#3 to advance past color pattern
2) i/o and sound test: use buttons 1,2,3 to select and play sound/music
- CPU0 manages sprites, which are also used to display text
irq (0x10) - timing/watchdog
irq (0x30) - processes sprites
nmi: wakes up this cpu
- CPU1 manages the protection device, palette, and tilemap(s)
nmi: resets this cpu
irq: game update
- CPU2 manages sound chips
irq: update music
nmi: handle sound command
- The "BEAST" protection device has access to dipswitches and player inputs.
Genre: Scrolling Fighter
Orientation: Horizontal
Type: Raster: Standard Resolution
CRT: Color
Conversion Class: JAMMA
Number of Simultaneous Players: 2
Maximum number of Players: 2
Gameplay: Joint
Control Panel Layout: Multiple Player
Joystick: 8-way
Buttons: 3 - Punch, Kick, Jump
Sound: Amplified Mono (one channel) - Stereo sound is available
through a 4-pin header (voice of Wolfman Jack!!)
