UPDATE: If you have been using FreeSO on Linux prior to Update 70 (June 9th, 2018), you must redownload macextras.zip In this thread Rhys mentions that the steps to getting FreeSO working on Mac may also work to get it running on Linux and this is in fact true and doesn't involve the unnecessary complexities of wine! On Linux the game looks for The Sims Online files to be in a folder named game and that folder must be inside your FreeSO folder. For example, /home/dotequals/FreeSO/game/TSOClient/TSOClient.exe should be the original TSO game executable. Installation Instructions: Download and install mono for Linux from your package manager http://www.mono-project.com/download/#download-lin Download and install SDL2 from your package manager (On Arch the package was called sdl2, but on Ubuntu it is called libsdl2-2.0-0) Download and install rsync from your package manager if "which rsync" (without quotes) returns nothing as it's used during the client update process. Download and extract the Windows build of the game as normal. The latest build on http://servo.freeso.org (log in as guest) should work as a starting point. Download the Client artifact from here: http://servo.freeso.org/viewLog.html?buildTypeId=ProjectDollhouse_TsoClient&buildId=lastSuccessful&buildBranch=<default>&guest=1 Download The Sims Online files and place the files into a folder named game that lives in your FreeSO folder. If you can't copy the game from network or a windows drive, you can try downloading with GetTSO.sh by Fatbag from NioTSO http://wiki.niotso.org/GetTSO Make sure your system has all the dependencies listed before running the script Download the Mac Extras zip here: http://freeso.org/stuff/macextras.zip Extract the Mac Extras into your FreeSO folder (ex. freeso.command and all other files inside should be copied directly into your FreeSO folder). Make freeso.command and freeso3d.command executable with chmod +x freeso.command (also do this for freeso3d.command if you want to play in 3D). Run ./freeso.command or ./freeso3d.command from your FreeSO folder to start the game! (these run mono FreeSO.exe through your terminal) you will need to update at least once. IMPORTANT: UPDATING Updating FreeSO is more difficult. After the game's update finishes, the updater will not run. You must run freeso.command or freeso3d.command again, where you will see it performing the update in the command line. Additionally, the game will not properly close until you close the terminal window hosting it. This is pretty unclean, but it works for now. Check back at this thread or the Mac thread after updates just to check if this process has changed, or if you need new MacExtras. Installed packages can vary widely from system to system so make sure to read the terminal output as you go through this process to check for errors. GetTSO.sh for example, has an unlisted dependency on bc, but will complete just fine without it. Simitone: You will need to install mono and (likely) SDL2 from the above steps if you have not already done so. Download and extract the latest ReleaseOGL from https://github.com/riperiperi/Simitone/releases Because we aren't on Windows, ReleaseDX will not work. Don't download it. You will need to obtain The Sims Complete Collection files from a Windows PC and place them within a set of sub-folders inside your Simitone folder. For example, /home/dotequals/Simitone/C:/Program Files (x86)/Maxis/The Sims/The Sims.exe should be the original The Sims executable. If you're using the command line to make these folders, quotations or escapes are your friend. From your Simitone folder, run "mono Simitone.Windows.exe" or "mono Simitone.Windows.exe -3d" without quotes and enjoy!
