Wow thank you very much! EVERYTHING works now! All I need to do is tear a 360 controller open and split it in half on each side of the screen and fit my 6 amp hour battery then win!

Overall pic so far

My little 5 inch screen pic attached, it looks grainey but it has the plastic film still on for now till I get it inside a 3D printed case.

I have a mini 5 inch display which I have to use the following settings in my config.txt for it to work (which I can see the recalbox menu and its all good): # uncomment if hdmi display is not detected and composite is being output hdmi_force_hotplug=1   # uncomment to force a specific HDMI mode (here we are forcing 800x480!) hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt 800 480 60 6 0 0 0   Once I launch a game it goes to a different resolution and my screen goes blank or corrupted.   How do I translate the above settings to the nes, snes, n64 GBA, GBC, GB, Genesis, Master System emulators etc?   Thank you for any help in this matter, I will attach a picture of my test setup for my recalbox portable im making.
