Fuck yea, I've been playing Pokemon blue on my phone for months. Shit is classic but better than 99% of new games.
Why even pay money? I got a Game boy advance, Nintendo Ds, Nintendo Gamecube, Nintendo 64, Super Nintendo and a Playstation 2 emulator on my computer and it's awesome! My friend has a gameboy advanced emulator on his iphone aswell, and you don't even need a fast computer for that one.
I got the emulator not too long ago on my phone as well. I played the newest version out of utter boredom and too much money. Fun but there too many fuckin Pokemon.
