Hi, I’m from Holland too, but I’m 15.
I’ve also been doing things like that. The limbo menu is I think a difficult thing to modify because it has a lot of buttons and pictures, overlays and some more.
If you want to test it, make sure your .pk3 file begins with - for example - a Z and make sure it’s located in the etmain folder. Go to your server.cfg and set dedicated from (I guess default is 1) 1 to 0. Then start et and type in the console /exec server
This is how I do it, you’re server won’t go online, you can use this for anything, soundpacks, skins, I myself am busy with a loading menu for my clan. I hope I haven’t forgot anything, succes!
