While not exactly a save file, and a bit more complex to get up and running, there is one more tool I use to help navigate in the Unity version (and other Unity games) to quickly get to scenes (as well as do some other things). That tool is UnityExplorer (here is the github link for it:
You must be registered to see the links
)
This requires the use of an injector (BepInEx is the one I prefer) and while the instructions on the site aren't great for anyone who has never used BepInEx or tools like it before, it's fairly straightforward to install and use (look below if you're interested).
Among many other things, it has the ability to select a game scene, and jump directly to it, allowing out of order replay of most* of the content. Press F7 if the top menu isn't visible. Click Object Explorer to open the panel. And at the bottom is the Scene loader. It has a filter so you can narrow down the scenes, or you can scroll through all of them and find what you want.
Here is an example (I circled in red where the scene loader is and put in "beth" as a filter example).
If you want to use it (with windows), here is the quick and dirty "guide".
- Download BepInEx.
- Download UnityExplorer.
- Unzip the contents of the BepInEx zip file into the top level of the game folder (where the exe is).
- The zip should have 1 folder (BepInEx) and several files.
- Run the game once for BepInEx to do it's setup steps (usually just loading the game is enough)
- Under the BepInEx folder, new folders should have appeared, if you only see "core" something didn't work.
- Go to the plugins Folder and unzip the contents of UnityExplorer. I like to put it into a folder with the same name (and version) for better organization, but the files can also just go directly under the plugin folder if you're lazy
- Run the game, press F7 if the menu isn't there
- Enjoy?
