help about gameguard implement on grf

[Ace D Potgas]

Im trying to use ROshield v2.3 gameguard by Gerome. My problem is that i dont know how to add into the grf so that when player in my server updating their patch, they gameguard will be implement into

their .exe icon (for example mitsuro.ext). I try to add manually without adding into grf at my test server and it work. I just need help on adding the gameguard into grf format so that player can get the gameguard by just updating their patch client (autopatcher). Please help me

you dont need to put it in your grf, you have to put it on the root foler of your ragnarok

So, you mean i have to release a new patch for my server and let the player download the patch and paste it inside their RO folder? But if they gold the old client patch, they still can use it and bypass my gameguard at the new patch i release. Please explain so that i can understand Really appreciate your help

you have to use md5 hash check so they can't use other exe
