My Xperia Play should be arriving on wednesday and I am migrating to android from iOS. I'll be missing the jailbreak functions such as Cydia (and Installous) and was wandering, if there is something similar to that on the Android OS? More to the point, what are the best and where can i get the following emulators; N64, GBA, GBC, SNES? I know all about the FPSe and will be getting that. But I have heard that many of the other emulators have been taken down the from market. So what are the alternative methods intsalling them? and are they free?
