Review of Coolbaby X7 Famicom/NES handheld

[@gameblabla]

UPDATE : So my bad, it was actually written in the Aliexpress listings but you need to hold the Control button (the one on the top right) and then press SELECT to enable AV OUT and press START to disable AV OUT (LCD). The settings are remembered in memory. That still won't fix the 50hz issue out of the box tho but makes it better at least
