[Other] Fixing the grass animation in emerald

[imas234]

I changed the pallette of the grass in emerald but when the player walks throught it it reverts back to its original color. So, i basically need to know how to fix it because its really bugging me. I know we can fix it in NSE for firered but NSE provides no such feature for emerald (bias >.>).Could you guys please tell me how to fix it and if possibly point me towards a tutorial or something. (i've been looking for one but had no luck)

Also, idk if this is important but i know nothing about hex editing or script editing or asm for that matter. However, i will learn if i have to.
