Xbox One S
Not really. More like a chinese knock-off.
I found this locally for $20.
The emulation is all over the place. Some games play decently, others are tolerable and there are others where the playability is fooked.
The GBA stuff for the most part is fine. The Neo has slowdown and screen tearing. Some sound issues and the odd graphical glitch but overall not too bad on the SNES and MD side of things.
You can add your own stuff via SD card as well.
The system case is pretty nice. It would be ideal to stick a Raspberry Pi in there. Which I reckon is what I'm going to end up doing with this.
