Yuna SakashiroFYI, I played Odyssey in Horizons 4.0 mode last night, and even in base game mode!
It's really simple to make this work. All you need is the app "Process Explorer" from the Sysinternals Suite (free download from the Microsoft Store), launch Odyssey as usual, and then look up the properties of the EliteDangerous64.exe process. The app will show you the current directory and the full command line that the Frontier launcher uses to launch Odyssey.
Next you open a command prompt, use "cd" to set the same current directory, then paste the entire command line and append the parameter "SeasonTwo" (or "SeasonOne" if you want base game mode). Now exit Odyssey and press enter in the command prompt window to launch the game again with the modified command line.
The first change you will notice is the intro cinematic: it's the old one from Horizons. In the game's main menu you will see either the Horizons logo or the original base game logo, depending on the mode you chose. Everything works as expected: Horizons will hide the Disembark button, base game mode will prevent you from landing on planets, etc.
Instancing with other players is possible if they use the same game mode. Last night I tried open mode in Horizons 4.0 and actually saw another player in Shinrarta Dezhra.
Bottom line: If you need base game mode only occasionally to get your SRV unstuck, this little hack does the trick. You can uninstall client 3.8 and use those 20 GB for something else.
Half baked development and poor strategy decisions. Frontier excels in both.
