Received my GA330 just a little while ago. Woohoo! First impession was that it's smaller than I thought. From images I'd seen I thought it was a fair bit bigger. It is only a little bit bigger than the A320, it even fits in my offical Dingoo bag snuggly. My free gifts from Ownta were a santa hat and a carry bag. The bag is way too big for tha A330. Perfect fit for my Letcool though so it's still a bonus.
The GA330 is a nice looking unit with decent build quality. It feels a little light, and not quite as solid as A320 but not flimsy or fragile. D-pad and face buttons feel on par with A320. Shoulder buttons are an improvement in size and placement. They are easy to press and comfy to use. They are not clicky though and initially I thought felt a bit spongy.
Turning the unit on was my first dissapointment. The screen is not as vibrant or sharp as the A320. I have my my Dingoo screen set to 3 and that is brighter than the Gemei at full setting. The gemei has poorer veiwing angles too with the image washing out or going dark depending on wich way the screen is tilted. The screen also as a "soft" look, the images display just dont look sharp or crisp like on A320.
Had a bit of trouble selecting roms to play at first. Selecting internet games kept giving me a list of pre-installed games with .JGC format.Had to change "browse type" setting in the settings menu to "Directory browsing". System menu works pretty much like Dingoo native. Now when you click on a rom it gives 3 options. Single mode, create server and search server. Only have one unit so can't test multiplay. Also the first time you run a rom the system takes a screenshot and when you select that rom in the future the menu shows the pic as a preview.
Tested a few games - most Emulators seemed to run very well with the exception of sonic 1 on Megadrive/Genesis wich had obvious slow down. My unit also didn't come with a snes sim so it won't even recognize Snes roms.It also came with 2 3d games. 7 days and another, both in chinese ant the file extension now .cc instead of .app.
Anyway that's all I have time for now, Got to take daughter to ballet lessons. If people want to suggest games that were "problem games" on Dingoo I'll test them on Gemei later tonight.
