    54: ----
    55: 
    56: - The readme claims there is a GI-SP0256A-AL ADPCM on the PCB. Needs to be
    57:   emulated.
    58: 
    59: - Verify all clock speeds
    60: 
    61: - I'm only using colors 0-15. The other 3 banks are mostly the same, but,
    62:   for example, the color that's used to paint the gradients of the sky (color 2)
    63:   is different, so there might be a palette select. I don't see anything
    64:   obviously wrong the way it is right now. It matches the screen shots found
    65:   on the Spanish Dump site.
    66: 
    67: - What do the rest of the ports in the range c0-ce do?
