Goldsource dedicated server (HLDS) launcher. This launcher is aimed to make running a dedicated server easier and at the best performance possible.
Simply copy "HLDS Launcher.exe" to the server folder and start hosting!. (Server folder is where hlds.exe is located)
Just select the game/mod you want to host and the starting map, set max players, UDP port (port must be forwarded if running through a router), enable/disable VAC protection (Valve Anti-Cheat), set your settings and click "Start". If restart server after exit/crash is enabled, you must click "Stop" to close the server without restarting again.
This launcher should detect every mod installed but it was tested with the following mods and worked flawlessly.
