I've received mine.
TLDR : don't buy it
Device is light as a feather.
Screen is ok for the price, TN.
controls are mediocre, no way to configure them, don't expect to play fighting games with it.
Battery life is very low, not surprising with a tiny 500mah battery, you try an emulator you lose 5% battery.
Someone posted a picture of the inside on a chinese shopping website (not sure I can post the name), it has a "N300" CPU, lots of room for a bigger battery.
About the emulators :
Nes is "ok", I've tried Castlevania III it works fine, LOTS OF SCREEN TEARING
GB/GBC seem "ok" too, Super Mario Land 2 works fine, Batman couldn't do the spinning start logo and crashed
Pokemon Crystal works fine, once again tearing everywhere on GB/GBC games.
Snes works at like 80/90% speed on simple games (Castlevania 4) Mario Kart does not render the circuit (no DSP emulation ?) and you guessed it : TEARING.
Genesis/Megadrive is even slower, Sonic 1 is barely playable, sound hiccup everywhere, tearing, unplayable.
GBA is surprisingly playable for simple games, I tried Donkey Kong Country and Mario Kart both runs at near full speed with just some hiccups while loading, of course tearing is still there, emulator is not accurate Doom II is very slow and unplayable due to massive graphic artifacts.
You get what you paid for.
