Mister could handle Retrowave OPL directly without RPi.
Retrowave uses simple SPI control with /CS. ( it uses MCP23S17 IO expander to control YMF262 )
we need to change User Port of Mister into 4 line SPI ( CLK,MISO,MOSI,/CS ).
SPI protocol is simple ( we can find protocol info from Retrowave github source code and DOSBOX-X code )
