I ditched off all Android devices and believe it or not I actually went with a new 3ds. Easy to hack which gives you perfect access to 3de titles as well as ds games. The virtual console is also now easy to load games up with which grants perfect Nintendo emulation of gba, snes, gb, gbc and master system. Retroarch (via the 800mhz mode of the new 3ds) is more than enough grunt to cover other consoles like the Genesis, PC engine and old school Mame. All you are really missing at this point is consoles like dream cast and PSP. It really is an all round device for emulation these days.
