I've installed the retail version of Unreal (v205) onto my Windows 95 machine (see sig below) and have progressed through some levels, making saves along the way.

After installing patch 226f, I am no longer able to see the saved game entries correctly within the game.
Unreal sees the saves, but does not name them correctly. This is because somewhere along the way in the patch history, some of the Unreal.ini configuration was separated off into a separate .ini file called User.ini.
This new User.ini file contains, obviously, all data related to the current user playing the game.
Unreal.ini retains configuration specific to the system, drivers, world and the engine.

So I found the following section in 205 Unreal.ini:

1[UnrealI.UnrealSlotMenu]
2SlotNames[0]=Vortex Rikers 21:33 May 22
3SlotNames[1]=NyLeve's Falls 22:22 May 22
4SlotNames[2]=Rrajigar Mine  21:30 May 23
5SlotNames[3]=Depths of Rrajigar 21:31 May 24
6SlotNames[4]=Sacred Passage 22:00 May 25
7SlotNames[5]=..Empty..
8SlotNames[6]=..Empty..
9SlotNames[7]=..Empty..
10SlotNames[8]=..Empty..

and I used the above to replace the following in 226f User.ini:

1[UnrealShare.UnrealSlotMenu]
2SlotNames[9]=Saved game
3SlotNames[0]=Saved game
4SlotNames[1]=Saved game
5SlotNames[2]=Saved game
6SlotNames[3]=Saved game
7SlotNames[4]=Saved game

These saved games from version 205 can be opened in version 226f but once I proceed to the transition area between the end of the current level and the beginning of the next, Unreal crashes and an error occurs:
The error as displayed in the Windows GUI:

Included is parts of the unreal.log. The following is where the save game is loaded from the main menu:

Ironically, this error can still be found today in the UE4 SDK developer tools when building your own games if a saved game is corrupt or missing.
Has anyone been able to successfully use Unreal saves from previous versions and then use the same saves once the game has been patched to a later version?
If anyone also knows a workaround to the error occurring above, I'd really appreciate it.

Yeah, you probably can't do that, they must have changed things significantly between patches.

You could just load into the map you were in and include the all the weapons you had. That should work sufficiently, no?

Sometimes. I did load some initial release saves in later ones fine, though editor sprites reveal themselves in places and I think one of the later versions would just disable input completely.

It was the same thing I'd already thought about as a last resort.

Realistically, I can't see how there is a way it is achievable as many improvements that would have been made between the two versions, potentially improving the save/load functionality at the same time as deprecating some of the original function calls the save files may be looking for.
