Thanks for the info, do you reckon the A320 is a better overall machine? Or do you know of something else that beats the lot? I want something small that will fit in my pocket. I have a archos gamepad that is great for emulators but a bigger screen means its more home based rather than carry everywhere!
It is difficult to say. I like them both a lot. More than any android console I own. To put it simply, they are more "playable" even though emulation is some cases worse than in Android. I suppose it has to do with the form factor and the excellent DPADs they have.
The best things about the Gemei are the price (I got mine for 35 dollars at DX) and that CPS2 and NG run almost perfectly (you can even run the heaviest roms like Metal Slug 3 or Marvel Vs Capcom), also the bumpers (R/L) are the best in a portable I have seen. Only some CPS2 bullet hells and some MVS games like later Metal Slugs require swiching off the sound to have a good framerate. The DPAD is very good, much better than android any dpad so far (note that I havenīt tried the Q88+). And the battery is amazing, around 5-6 hours fully charged (use a 1.5 mA USB charger, the one included won't charge this thing, typical chinese stuff),
I don't have a 320, I have a 330, and well. It looks slightly better in terms of construction quality (specially the screen is "crispier"), although the performance for CPS2 and NG is sluggish (even without sound). It is also twice as expensive, maybe more. On the other hand, it emulates almost perfectly anything else (SNES, MD, GBA, NES) using custom emulators (pocketsnes, double buffer MD emulator,...), and you have a plethora of emulators and apps than don't run in the Gemei (Temper, again is a must). Finally, the DPAD is awesome, the best I have tried in a handheld. The bumpers are crap, unfortunately.
It is a trade off, really. So my advice is that, unless you are short on cash, you are a Neo Geo freak or you want to play CPS2 bullet hells, go and get a Dingoo. Be prepared to spend some time changing emulators and looking for the right roms, though. There is no such thing as Google Play for these things...
