No: only the 'saves' directory/folder (you might be able to copy new updates over old ones of the same part, but I don't know). Did you start on part 1 though? Chapter 22 is part of part 3. I think part 1 ended on chapter 12, and part 2 ended on chapter 20. If you only started with recent updates you skipped ahead and missed almost the entire story. It was split into parts because part 1 became too large (several GB) for most download sites, etc.
You DO NOT need to copy your save folder on Windows or Mac. RenPy saves in the persistent location in AppData (on PC), and somewhere else on Mac. You can delete folders of most RenPy games (any that didn't manually change the code to disable the persistent save), and your saves will still be there when you install and launch the next version (within the same Part of the game).
I was on TFS Update 19d. I downloaded and extracted TFS Update 22c. I copied the saves folder from the 19d to the 22c like I've always done, but when I load the last save (made at the "save here" prompt), I just get thrown back to the "Start Load Options Patreon About Quit" screen. Any clue what I'm doing wrong ?
Do not combine folders from different updates.
Do not load saves from Part 2 (Updates 13* through 20*) in Part 3 (Updates 21* through 22*) except for the specific place at the end of Part 2 (Update 20e) where it says to save, with a giant "SAVE NOW" screen. The same thing goes from going from Part 1 (Beta release through Update 12* and V2) to Part 2. When Part 3 ends and Part 4 begins, you'll have to do the same thing again.
You cannot go directly from 19d to 22c. 19d is Part 2, and 22c is Part 3.
Here's the actual way to play this game from start to current content (you specifically can skip steps 1 and 2, since you have a save from 19d):
- Install and Play Part 1 V2 (this is basically a cleaned-up version of Update 12a)
- Save in Part 1 where it says to save. You do not need to copy this save folder.
- Install and Play Part 2 Update 20e in a DIFFERENT folder than Part 1 V2. DO NOT COMBINE FOLDERS.
- You will be able to load the save from step 2 above. This is the only Part 1 save that you can load into Part 2.
- If you've got saves from any previous version between Updates 13 and 19, you must still launch Update 20e.
- Save in Part 2 (Update 20e) where it says to save. You do not need to copy this save folder.
- Install and Play Part 3 Update 22c (as of today) in a DIFFERENT folder than Part 1 V2 and from Part 2 Update 20e. DO NOT COMBINE FOLDERS.
- You will be able to load the save from step 6 above. This is the only Part 2 save that you can load into Part 3.
- When you're caught up, roll back a few, save, and then you can delete the folder.
- When Update 23 comes out, just install and play. Your save from step 9 will work fine. Nothing else is needed.
- You can keep doing it this way, even skipping a few updates, but only until the end of Part 3. At the end of Part 3, you'll have another "SAVE NOW" screen, just like you did in steps 2 and 6 above.
