Hello folks, As I use Linux, I found starting a multiplayer game session in Wine-based Renegade X little troublesome and frustating: Wine doesn't support the way Renegade X loads multiplayer server lists. Typing an IP address into the launch command of the game is also very unpractical method to start the game. That's why I decided to develop something useful to simplify server selection process for a Renegade X on Linux. The following bash script downloads servers.jsp file from the web, breaks it into pieces and, as a result, shows a quite readable updated Renegade X server listing in your bash/terminal window. I did the script with my very limited bash scripting skills so please feel completely free to improve its functionality in all matters. At the moment of writing, it's just ugly & awful, but at least it does what it is expected to be done. When you execute the script, a terminal window will be opened (unless you execute the script in a existing terminal window) and you're asked for a valid server number. Just pick your favorite server from the showed list and you're ready to play the game online. Recommended installation steps for this bash script: 1. Download the script below and save it into your preferred location (e.g. /home/john/launch_renegadex.sh): #!/bin/bash #The goal of this script is to provide a human readable, simple game server #list & selection tool for the linux users of the Windows game Renegade X. #I know the scripting is quite awful, so if you have time, interest and #skills to improve the script written below, please feel free to do so. #Download a temporary, local copy of Renegade X server listing: wget -N http://renegadexgs.appspot.com/servers.jsp -P /tmp/ ################################################################################ #THESE VARIABLES PARSE THE FILE servers.jsp INTO PIECES.

If you have a desktop shortcut file for your Wine-based Renegade X installation, please open that desktop file in your preferred text editor. 3. Copy the execution command from the line starting with string Exec (do not copy string Exec=, just the command itself) 4. Open the downloaded bash script. Scroll down and paste the copied game execution command to the end of the script file. Replace the existing one (/usr/share/playonlinux/playonlinux --run "Renegade X), but just remember not to delete variable $selected_server as it provides the vital server IP information for your Renegade X launch command. 5. Open the Renegade X desktop file again. Go to line Exec=. Delete the existing command in that line. Paste the bash script execution command as a replacement (e.g. Exec=bash /home/john/launch_renegadex.sh) NOTE: I've found that, for some reason, sh command may not work with the current script structure. Try bash command instead as shown in the example above. 6. In the desktop file, edit line Terminal=false to Terminal=true. If this line doesn't exist, just create it. 7. Save the Renegade X desktop file and execute it. A terminal window should pop up, asking you for a valid multiplayer server:
