Just got my Windows Phone 8X a couple of week ago (Absolutely stunning phone if anyone is interested) I managed to get an emulator onto it and currently enjoying Pokemon Sapphire. Basically I've come armed with the following questions, help a pokebro in need:
a) Does anyone know if you can trade a pokemon you've caught on a ROM in anyway?
b) Looking for a pokemon game which does has something extra, anyone know any .gba roms which have like, a randomiser on it or something? (Preferably Emerald)
c) This ones a bit of a long shot but just in case I get lucky, does anyone know if there's someway I could get games like Diamond and Pearl running on my phone? The emulator only runs .gba files at a maximum but just wondering if anyone knew any other way.

Cheers in advance!
