Currently i am working on a PiGRRL Image / addon (based on Batocera Pi0).
I added the SPI-driver for the display and my both addons (C64DTV based on vice and AmigaCD32 based on uae4arm).
This weekend i try to finish my work (GPIO-Buttons and display fps-tweaking).

VICE is really nice and smooth on the RPI0, it should be included by default.
