This I swear, will be the final bit on virtualbox for a while, and I believe I mentioned Android (or phone linux as its never known as) last time. So here goes, I had about 3 different ISO.s of this before I finally found a copy that worked. My first got stuck in some sort of command line hell even after rebooting, the second installed fine but when it came to boot proper it got stuck at the loading screen (Ironies I'm emulating a bricked tablet) the final version I found works well and I've come to if not like Android then on a level abide it.
You'll need to disable the mouse to actually do anything with it, and I've browsed the Google play store and even watched some porn online (even though flash doesn't work with it so watching any video is pointless). Also as its basically running in a box you could essentially click on all those ads on the side and not suffer any consequences doing so, (We've not installed adblock so the screen area looks massively cluttered and untidy.) On the plus side I get the joy of playing android games except what I've installed so far requires an update or my virtual box is not considered a proper phone for downloading through google play.
So far I have Disgaea Netherworld (either not supported or not let us download) and PPSSPP which doesn't run for me either on android or computer.
NEO GEO Gold SNK step in.
Didn't expect to find this via Dr. A's twitter feed. SNK have publically disowned TOMMO distributors of the NEO GEO gold X handheld console, which we translated the specs of way back when. The console itself wasn't that great and was basically a system on a chip running a version of FBA so maybe its for the best.
