Got my hands into a raspberry pi zero w and decided to do a portable arcade machine with an snes controller.
Why an snes controller? It barely provides enough space for everything, but it does have 4 buttons + 2 triggers and it’s still flat and small enough to carry in the pocket. A nes controller would provide more assembly space, but with less buttons and a square shape.
So basically I used a raspberry pi zero w, a micro sd card, a lithium battery charger, a lithium battery from my small syma x5c quadcopter (3.7V 500mAh - if buying one there are already more powerful ones with the same form/size), an snes controller (got one on amazon), a small power button, a mini hdmi to hdmi converter and some wires.
Then it’s just some patience wiring all together and testing it. Getting a retropie distro into the sd card, adding some roms on it and configuring the snes controller to work via the gpio’s.
I inspired myself in this 2 tutorials:

Don’t forget to configure the wifi and enable the ssh before closing the remote for further management/copying roms into the pi.
