[Battle] How do you give Hyper Beam its old gen 1 reset effect in Pokefirered?

[Gntc Jckhmmr]

I would like to give Hyper beam it's old generation 1 effect where Hyper beam doesn't need to recharge after killing the foe or substitute. I'm using pokefirered.

I think I need to edit the recharge effect in these files:
data\battle_scripts_1.s
src\battle_script_commands.c

How do I go about this? I'm reading Fell Stinger from the pokeemerald battle engine and reading the same files as a reference because it has a similar effect. I assume I have to edit battlescript_FaintTarget on data/battle_scripts_1.s and add some if statements or something for the recharge effect. Yeah I'm getting lost.

Start by looking at how fell stinger works:
BattleScript_FaintTarget uses the command tryactivatefellstinger, which is defined here. It calls a "various" function with the id VARIOUS_TRY_ACTIVATE_FELL_STINGER. That will then activate this bit of code in Cmd_various that checks if the effect should be applied and applies it.

You could similarly add a new command that is used in BattleScript_FaintTarget and checks if you fainted the opponent with hyper beam and removes the recharge flag set in BattleScript_EffectRecharge. This bit of code might help you with that.
