Joyrider does it again!
Here is the native dingoo gnuboy (Game Boy & Game Boy Color emulator) with sound, save states, skins, and full screen:http://dl.openhandhelds.org/cgi-bin/dingoo.cgi?0,0,0,0,71,159
This is my favorite emulator on Dingoo.
The Game Boy was my first portable gaming console and I kind of regret selling/trading off my extensive collection many years ago.
Back in those days I had to lug around the original Game Boy, external battery/power adapter, game boy light/magnifier, and many game cartidgess in a hard case.
The hard case looked like a giant Game Boy and I also had the official Game Boy fanny-pack
Now I can potentially tote the entire Game Boy library [and more] in the little Dingoo alone, no cartridges, no external batteries, no fanny-pack.
The Dingoo is a great all-in-one Game Boy.
