Re: Android for Emulation?
Well, you know that thing they call a laptop is perfect for your situation. Though a notebook might be better, I recommend getting a cheap laptop throwing 100$ into it and then putting linux on it for kick-butt tier speed and portable emulation. However I've heard that the android can emulate GameCube games and that you can connect a PS3 and PS4 controller via bluetooth to it. If it can take the GC it can take the PS2 I'm sure, it's just a matter of space and emulator application. If you can't find it on the appstore try here HERE that's an apk torrent site that might have it I don't usually go there but you never know.
