I had a similar question in the past during my first Gameboy and took this into account on my second build. I programmed all keys in the Teensy as much as possible as the standard keyboard layout. Finally now I can move through most of the retropie configs. Here is my adapted script I used to progra...

Ordered! Thank you!

One question is just coming up: Regarding the autosave on exit of emulators. In the moment this is managed by trigger one button mapped to exit the emulator (escape).

I used the same HDMI screen and I am happy. Only disadvantage: the screen size is something like 16x9. So the cutout from your screen boarder is quite different due to the geometry.

Same idea: I placed low bat and charging LEDs in the rest of a cartridge. I used flat heat leds from ebay: http://www.ebay.de/itm/140748947687?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT Finally another good idea I found somewhere was to put the Raspberry Zero into the cartridge shell...

Had a similar issue when testing the teensy: one button key pressed was detected bouncing. Finally it was my script on the teensy: same keyboard command was used from two inputs!
