Autosave gets corrupted in Shivers

[neuromancer]

We are playing Shivers (from GOG) using scummvm compiled from this revision: ​https://github.com/scummvm/scummvm/commit/8d22aa3af1e. Every time we try loading the autosave results in the game showing a screen saying that it is corrupted and it should be deleted. Perhaps scummvm is automatically saving where the game does not expect it?

Hello and thanks for reporting this. Can you please attach your Shivers save files? You can find the location of these files at: ​https://docs.scummvm.org/en/latest/use_scummvm/save_load_games.html#location-of-saved-game-files

I'm most interested in the save file for the broken save, but if you could also attach one of the working saves to compare, that would be a big help.

I work on the Sierra games but Shivers is one of the ones I'm least familiar with, so I'll need a little hand holding. There are two forms of autosaving: the ScummVM feature and any autosaving that the game itself does. Do you happen to know which one created the corrupt save? Another way of asking this is: does Shivers itself have an autosave function? (That's an example of the kind of thing I would know if I knew this game!)

Can you also include what your ScummVM autosave setting is? That's under Options \ Misc.

I just attached the autosave (000), a working save game (001) and something else I'm not sure what is but looks like produced by the engine. My autosave setting is "every 5 minutes"

Thanks! I see now that Shivers does have its own autosave feature. When enabled, it saves to the current slot. The ScummVM autosave saves to slot zero.

This should fix it: ​https://github.com/scummvm/scummvm/commit/e01775bcae1696092713647946295e4974cb3d17

The save file is fine, but we had a bug when loading any save from slot 0 in Shivers and Phantasmagoria 2. Note that this save is at kind of an odd spot, but loading it now gets the same result as if you move the file to a normal slot and load it from there.

Let me know if this works for you.
