You might need reading glasses for this teeny RetroPie. Shared on Instructables:
Both Raspberry Pi Zero and Raspberry Pi Zero W is ok. WiFi version can make subsequent setup easier but in contrast it may draining more power continuously, i.e. shorter battery life.
Waveshare released 2 LCD HAT for RPi Zero, both have a tiny square LCD. The newer version have a 240 x 240 1.3″ IPS LCD, this resolution is capable to emulate many retro game console.
To closely fit for the Waveshare 1.3″ LCD HAT, it require a 8 mm tall 2 x 20 pins header. But I cannot buy one with 8 mm tall, so I will modify from a 12 mm tall pin header.
