TODO:
- understand the ball hit sensor
- simulate the sensors (there are still some shutter errors/defender errors that pops up)
- Hook-up timers for shutter/defender sensors (check service mode)
- Dip-Switches
Brief hardware overview:
------------------------
Main processor - 68000 16Mhz
Sound - Yamaha YM2610B
Taito custom ICs - TC0400YSC (m68k -> ym2610 communication)
- TC0260DAR (palette chip)
- TC0630FDP (Taito F3 video chip)
- TC0510NIO (known input chip)
DAC -26.6860Mhz
-32.0000Mhz
