I´ve made an new GBZ with an 800x600 HDMI Display....
Powered by Helders Retro PSU and Tinkerboard 3.0.
This time I used a original GB case from a broken unit.
Display can be found here:

The rest ist a classic setup with an AIO Board by Tinkerboy. All Helpers are designed by myself.
The HDMI cable is also soldered by myself. The screen has to be setup for the first time to achive a permanent "HDMI In" function. I reduced the screen brightness to 35% because it´s to bright.

Desoldering all the connections pins from the driverboard must be done. It runs OOTB by 5V, so no voltage tweak is needed.
Sound can be taken direct from the L+R analoge pins of the pi3a if you use a common ground button pcb and GPIO setup.
