Hey /vp/, I'm ding a randomized nuzlocke of Fire Red and I acquired a Porygon from the Magikarp salesman. Normally I'd have boxed it but I turned trade evos off so I'm waiting for it to evolve.

Thing is, I have no idea how. I have every stone but a Sun Stone, it's level 32 and I'm pretty sure it's max happiness. Do any of you know how to evolve him?
