::sigh::... and again... more issues. as you can see, there's a bad delay when pressing the directional buttons, and when it finally does register the press, it repeats the input twice or more times. the ABXY buttons are also having problems, sometimes not registering my press at all!
Which emulator? From the looks of it I would assume, that you use controls that you mapped with the mapper and not properly placed them on the screen. Did you use remapped touch controls or hardware mapped buttons in this video?
Overall, I am very satisfied with my GPD XD, many of the things people complain about are more about personal tastes then everything else, e.g. the D-Pad. I am perfectly fine with it, it's on par with the D-Pad of the New3DS. I personally prefer the D-Pad on the Vita which to me is the best D-Pad any handheld ever had, but I know there are many people who hate the Vita D-Pad. In the end the question is, is it possible to play games with the GPD XD D-Pad without problems? And from my experience that's perfectly the case.
@sere83People don't say it's a cheap device so you shouldn't expect anything, they say that the XD is a fine product for it's price, that's something entirely different.
The device you came up with looks nice, but there is now way I would be willing to pay $225 for it.
I paid ?155 for my GPD XD your device would be ?207 and it would give me no benefits. No emulator would run better with 3 GB then with 2 GB, I would never use an Accelorometer, the 2200mAh battery would be a huge step back, the GPD XD comes with a 6000mAh battery and the AMOLED wouldn't make that difference up.
