GOG Migration with Offline Mode #3

Closed LinnielDW closed 3 years ago

Tool cannot migrate from GOG to steam if you save while played it in offline mode.

I decompiled the overcooked2 source code and had a look around. It uses SystemInfo.deviceUniqueIdentifier as the encryption pw if it cannot find it. I created a local unity project to find out what mine was, but this can be automated.

Proposal to decrypt file using SystemInfo.deviceUniqueIdentifier if argument not found.

Are you sure it doesn't appear in the savegame path in AppData similar to Steam/GOG ID? How big of a deal is it to link against Unity SDK (like, is this a Nuget package or do you need to install it separately)?

Instead of the path \Overcooked2\*.save I found mine was saved in \Overcooked2*.save. At work right now so I can't give you the exact method call, but from what I saw of the decompiled source, this happens when the userInstance.signedIn != true. I don't know how this happened. Was just trying to get migrate my gf's save file after I picking up OC2 gourmet edition on steam due to the sale.

SystemInfo is part of the UnityEngine package but when I tried running it from VS using the Unity Nuget package I got an ECalls forbidden error. Didn't take a look further into it, figured I missed some kind of config. So I just booted up Unity and ran the same method from there in a blank scene.

well, if it doesn't link smoothely I'd rather have it as a different tool, do you wanna create one and I'll link it from the readme?

Sure thing. Threw together a little applet, repo here: https://github.com/LinnielDW/UnityDeviceUniqueIdentifierHarness
