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.
