Phone for PPSSPP

[thedicemaster]

you really need a phone with either an SD card slot, or at least 32GB storage.

nvidia shield(high performance, but not a phone) and Xperia play(lower performance) have the advantage of built-in controllers, the Xperia play buttons are actually pre-programmed into ppsspp.

my preference goes out to the note 2 and a separate mobile controller(I use a ps3 controller modded using lego technic) in part as a silent protest against the vita's emulator's limitations.
it has about the same size screen and the same type(close to 5" oled), but can also handle games at far higher resolution.
the vita runs psp games at 480x272 upscaled to 960x544, while the note 2 easily renders psp games at 960x544 upscaling them to 1280x720(it's hard to see but it might even be rendering them at 1280x720 if buffered rendering is off)
the large screen is really nice to have.
