      Driver for the Miuchiz handhelds
      CPU: ST2205U;
          XTAL: Y1 16MHz
          XTAL: Y2 32.768KHz
      LCDC: ST7626 (https://www.crystalfontz.com/controllers/Sitronix/ST7626/)
          the ST7626 is embedded into a epoxy part just below the screen glass with the flex cable attached to it
          it has internal 98x68x16bit ram
  
      Extremely preliminary
      The inputs are mapped in an input array, but aren't actually hooked anywhere yet.
      The screen is a dummy and just displays nothing for now.
