idea Hacking soul silver with megas and pokemons of X & Y

Hello fellow pokefans.Its nice to meet you all.

I am a new member here and i hope tthis is the right place for my question,if not then excuse me.

I am a fan of gen6 pokemons and inbattle mega evolutions. Also soulsilver is my fav game till now because of following pokemon. So i searched for GBA and DS hacks with mega evolution and gen 6 pokemon and found some .But all seem to have evolution just like using stones on Evee.But i am sure i saw someone posting a code for inbattle mega evolution in this forumn.

So i would be greatful if someone would direct me to some hacks similar to X & Y game mechanics either in GBA or DS

Thank you and please excuse if i missed any forumn rules and notify me so that i can correct myself.

Welcome to the forum! I don't know whether this should go here or in ROM Editing Help, but more importantly, I'm not sure if this can even be done. Maybe, though
