Notes
-----

Route 16:
        - Route 16 doesn't have the SN76477 chip. There is space on the PCB
          but it is not populated.

        - Has the added ability to turn off each bitplane individually.
          This looks like an afterthought, as one of the same bits that control
          the palette selection is doubly utilized as the bitmap enable bit.

        - New code to better emulate the protection in Route 16 was added in 0.194,
          but it turned out to harbour a bug (see MT 07310). Therefore the previous
          patches have been restored, and the protection routine has been nullified
          but is still there in case someone wants to revisit it.

Stratovox:
        - Has almost *electrically* identical hardware to Route 16 with the exception
          that it is physically different (2 PCB-set connected with flat cables) and
          Stratovox has the SN76477 chip and uses a DAC for voice. There are 3 volume
          pots on the PCB. One for music, one for speech and a master volume.

Space Echo:
        - When all astronauts are taken the game over tune ends with 5 bad notes,
          this appears to be a bug in the ROM from a changed instruction at 2EB3.

        - Service mode shows a garbled screen as most of the code for it has been
          replaced by other routines, however the sound tests still work. it's
          possible that the service switch isn't connected on the real hardware.

        - The game hangs if it doesn't pass the startup test, a best guess is implemented
          rather than patching out the test. code for the same test is in stratvox but
          isn't called, speakres has a very similar test but doesn't care about the result.

        - Interrupts per frame for cpu1 is a best guess based on how stratvox uses the DAC,
          writing up to 195 times per frame with each byte from the ROM written 4 times.
          spacecho writes one byte per interrupt so 195/4 or 48 is used. a lower number
          increases the chance of a sound interrupting itself, which for most sounds
          is buggy and causes the game to freeze until the first sound completes.

vscompmj:
        - Stuck notes (constant tone) in-game after the mahjong tiles are laid down.

Speak & Help

Single layer re-engineered pcb, very tidy and working.

All dumps are in label.location format, see the two
included photos for one of the pcb with and without the
speech? daughterboard plugged in for verification.

Roms are all mitsubishi 2716, proms are fujitsu MB7052.

Unique speech, as detailed in video, seems will require additional work to emulate correctly.
