User Manual

There may be some bugs with the original software so there is an updated Zerabosk version which fixes some issues (but other issues may still remain). Comes with a clear reproduction GB cart shell included separately. You will need to modify the cart shell – cut out the top part of the shell as the PCB sticks out, check the picture.
