/***************************************************************************
Entertainment Sciences Real-Time Image Processor (RIP) hardware
driver by Phil Bennett
Games supported:
* Turbo Sub [2 sets]
ROMs wanted:
* Bouncer
* Turbo Sub [later version] (uses 512kbit graphics ROMs)
Notes:
* 'turbosub' executes a series of hardware tests on startup.
To skip, hold down keypad '*' on reset.
Todo:
* TMS5220 speech? The game sends speech play commands to the sound
CPU but they're ignored. The speech data seems to be stored in
the upper half of the (banked) sound data ROMs but this is never
accessed. Maybe the speech data was unfinished and only the later
version of Turbo Sub has speech?
* Determine if line drop outs occur on real hardware. Overclocking
the RIP CPU eliminates them.
* Implement collision detection hardware (not used by Turbo Sub).

Information
===========
The game processor is responsible for gameplay and reading inputs
(keypad, ADC and digital). It shares 16kB of RAM with the frame processor.
According to the schematics, it also has access to collision detection RAM
and palette RAM used by the video system.
The frame processor organises data supplied by the game processor into a
suitable format for the video processor and video hardware. It shares 8kB of
banked RAM (Frame Drive Table) with the video processor.
The video processor instructions are stored in 6 PROMS (which are ARE
NOT DUMPED).
Each CPU has a R/W status port used to communicate with the other CPUs
and hardware.
