Hacking I can't patch my ISO with a Gecko Code

[Rayz0rum]

So I want to patch the green edition of Mario Kart Wii Deluxe with the no-lag multiplayer cheat code but I try to do so using wstrt to patch, I get this
! wstrt: New section would overlap 1 existing section -> ignore: GCT
* File not modified: DOL:MarioKartWiiDeluxe/sys/main.dol

So I used the --force command and I'll verify if it works

 

[Rayz0rum]

it works
