Ok so i finally recieved this thing and i can say that it is a huge letdown. The only pro is that it is cheap and that it is 7 inches but personally if you want emulation that works ok then get a RS-97 instead for a similar price or spend more and get a GPD XD.
Lack of memory means that the thing is dog slow. So slow that it is near unusable. I had to actively search for a Snes emulator that actually ran at fullspeed.
SuperRetro16 was the only one that worked well on it for me. Snes9x EX & John Snes ran terribly slow.
Battery life is terrible on this thing. By that i mean half an hour to an hour max.
L and R buttons are extremely uncomfortable.
Also Start, Select and the Analog seem to be a different joypad to the D pad, a,b,c,d,l,r buttons so certain emulators do not work well with it.
