Shutdown board installed and worked fine... Just unhappy to have more wires inside the device :( To Camble: I struggle to upgrade my second build because in this my raspberry board is slightly covered inside the game cartridge tray. I have access just to GPIO pin 17 and upwards... I know your Power ...

No it isnt. You can link it to the price. All higher relolution displays in the scope of 3.5 inches are more expensive.
The only advantage in my mind is the digital connection compared to the analog composite.

Honestly not a lot... I started booting both of my builds on the same time. One on 100MHz, the other on 83MHz. The 100 MHz Version was maybe 2-3 sec. faster in booting. My conclusion: don`t spent so much in high speed expensive SD cards if you aspect a huge increase in speed.

Sorry if this topic is already known... Do you aware that a Ultra High Speed (UHS) mode on SD cards is not used by default on the raspberry PI? The SD card access speed needs to be "overclocked". Take care: not all SD cards support this. In this case you can reduce the setting until it works... I go...

I had a similar issue with the small resolution especially to be able to read the game titles. Finally I installed another theme, optimized for this needs. Look here for an idea:

A general way of working: run up your display on 12V and measure around the big capacitors and maybe on the terminals from the voltage step down converter WHERE you find 5V or something slightly above 5V: maybe 5.15V. This is your point for bridging or at least a better reference for further investi...

Pictures from inside: maybe during the coming days. The reason: In the moment I closed my build by a thin boarder of aluminum tape on the edge of both half shells which I don`t remove for minor issues. It is really nice and well sticky :-) I had to remove the screw holder in the battery bay for my h...

I remember first I did it via the terminal in mac and something with the dd command.

Play with your groud: best would be to use a shielded composite connection. Maybe you find some old headphone wires or composite extensions. Second: connect the shield to the raspberry ground next to the composite pad. If no effort try any other grounds in your power distributions.
