I was browsing the Aliexpress video game console section the other day and found this: https://www.aliexpress.com/item/Quality-2-0-Monon-Video-Game-Player-Console-with-100-Games-and-4-Game-Cards/32768266847.html?spm=2114.13010608.0.0.hKCqEv
I thought nothing of it, thinking that it was just another emulation machine like other pvp machines, until today when I decided (because I was bored) to look into it.
I only managed to find one website about it: https://tieba.baidu.com/p/3501829953
From what I found out, it is made by a company called M&D.
It has a 320x240 TFT screen and 3-5 hours of battery life. I think it uses AA batteries, but I don't know for sure as neither the post above nor the listing say.
The post above says that the quality is good and that it doesn't feel like a knock-off console. Also, the graphics are apparently on par with the GBC/GBA but the gameplay feels like an old java phone game. The cartridges are slightly thicker than a GBA cartridge and slightly shorter.
The company (M&D) supposedly has said they will publish a new game every month.
The baidu post above is dated 2015, but the picture in the listing says copyright 2016 (could the listing be a more powerful version?)
It gives a whole bunch of games on the back:
I bought one and it should be here within twenty days. There are currently over 9,000 left if you want to get one yourself
(Also, I hope that guy's hands are tiny otherwise it's going to be a huge box)
