Overriding item effects?

[Celyna]

Hi,

I wanted to try my hand at writing mods, and the first thought that came to mind was editing Soul Dew to its original function from before Generation VII (increasing SpA/SpD by 50% for Latias/Latios). Can anyone point me to the scripts that I'd need to edit for this?

Script PokeBattle_Move, remove the "#" before the lines 2225, 2239, 2280-2285, 2420-2425, 2476, 2490, 2539-2544, 2661-2666

 

Same script, add "#" before the lines 1301-1305

 

Lastly, replace lines 2252 and 2253 with

        gl2=(gl2*1.0*dewBoost*avBoost*evioBoost*dssBoost*fgBoost*stagemul[gl3]/stagediv[gl3]).floor
        gl1=(gl1*1.0*dewBoost*specsBoost*dstBoost*lbBoost*fbBoost*minusBoost*plusBoost*solarBoost*batteryBoost*stagemul[gl4]/stagediv[gl4]).floor

and lines 2503 and 2504 with

        gl2=(gl2*1.0*dewBoost*avBoost*evioBoost*dssBoost*fgBoost*stagemul[gl3]/stagediv[gl3]).floor
        gl1=(gl1*1.0*dewBoost*specsBoost*dstBoost*lbBoost*fbBoost*minusBoost*plusBoost*solarBoost*batteryBoost*stagemul[gl4]/stagediv[gl4]).floor

This should restore Soul Dew's effects (didn't test it, additional edits might be needed).
