[ASM & Hex✓] Can i make a Pokemon devolve[EM]

I'm using emerald

Ok what I was thinking was every time a battle ends some pokemon(that I choose myself) will devolve
To their earlier stage
Just like megaevoloution



I need it bc I want to make mega evolutions in emerald (it will be a mega evo which is a mix of real mega evo and evo stones mega) but I think
That the one at this place https://www.pokecommunity.com/showpost.php?p=8982294&postcount=243 is too complicated for me

So pls help, even if you have another solution and know how to do this
Then pls post both

The binary version of Egg's battle engine has mega evolution included, but not sure if you might find that easier or harder to implement than the method you already know about.
