* Hold '*' during the game to access the operator menu.
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?
* TMS5220 speech. The game is sending speech play commands to
the sound CPU but any speech code greater than 2 is ignored (see $EC26).
I think most of the speech data is stored in the upper half of the
banked sound data ROMs but I don't know how or when the ROM
bank is switched :/
* Determine if line drop outs occur on real hardware. Overclocking
the RIP CPU eliminates them.
