You'll essentially be launching jampDed.exe, but there is a specific way to do it that you can't do simply by clicking on it. To launch the server, just follow the instructions in readme.txt. Otherwise, you have just v1.0 (unless you manually patched the game yourself, you would know). If you have the steam version, you should have v1.01. Again, make sure you select the correct version. There are a variety of different servers you can host, depending on the mods you have, but for standard JKA, use this: ĭownload and then put those files in your gamedata folder. It's fairly easy to host a server and then friends can join either on the same LAN or across the internet as well.
