It depends. I suggest you have a Plusle in your party too.

I sorry but minum and plusle dont evovle. :(
Minun is a single-evolutionary form and so does not evolve.The contrast Pokemon Plusle is also single-evolutionary that has moves and abilities that compliment that of Minun's.
It dependes witch one is female. if the Plusle is female, you will get Plusle, and if Minum is female, you will get Minum.
Sapphire is better, but yes, emerald is good.
Raltz! :D
