[Question] Pokemon EXP Share like Pokemon X/Y

Hey,
first of all I hope you guys dont kill me for that question. :P

But is there any script or even a Pokemon hack with EXP share like in Pokemon X/Y?

Or isn't it possible to make a new or change a item in Pokemon?

I mean ... EXP Share script could be changed to be like in Pokemon X/Y, or just add a new item "EXP Share 2", for ppl who dont want to use the EXP Share 2... :/

I was searching for it, but diddn't found something... ):

I did have one once ill look for it and post it up if i havent deleted it

You should say whether you're doing a ROM hack or a proper game. And if you're doing a proper game, are you using Essentials?
