Daggerfall:Corrupted Savegames

Corrupted savegames continue to be a very annoying problem in Daggerfall, even if all available patches have been installed.  This article provides some known workarounds and also provides advice on how to avoid the problem in first place.

In most cases, if Daggerfall crashes to DOS when you try to load a savegame and the error message is 1002, 1003 or 2020, then a corrupted savegame is to blame.  Generally, the game-internal tool FIXSAVE will not solve this problem.

Avoiding Corrupted Savegames
The majority of corrupted savegames are caused by memory issues.  Therefore, the best way to avoid such problems is by replacing the memory extender that comes with the original game with a more advanced one.

One such Memory Extender is DOS32A. 
To setup the program, read the documentation on the program's original web-page or the else read the article on the DOSBox wiki. 
Use DOS32A whenever you run Daggerfall, preferably from the start of a new game.  Players have reported that by doing so you can effectively prevent corrupted savegames from occurring.
This Memory Extender should also be used when running DOS programs other than Daggerfall, including other DOS games that use a memory extender such as the once-popular DOS4GW.

Step-by-Step instructions for DOS32A
For those of us who can follow directions better than read pages of manuals, not sure what applies to us, here are some step-by-step instructions for getting daggerfall to work with DOS32A.
Download DOS32A, you should have SB.EXE and DOS32A.EXE (and other files)
Copy the SB.EXE and DOS32A.EXE into your \DAGGER directory (where DAGGER.EXE and FALL.EXE are)
IMPORTANT Make a backup of FALL.EXE, in case this messes it up!
COPY FALL.EXE FALLBAK.BAK
sb /R fall.exe

Now, when you start daggerfall normally (DAGGER.EXE), it will use the DOS32A memory extender instead.

Workarounds for Corrupted Savegames
There are some workarounds for corrupted savegames:
# Use the DOS32A Memory Extender (discussed above).
#* Very often an apparently corrupt savegame can be run again when using DOS32A.  In this case, you will need to always run DOS32A to keep your savegames working.
# Delete all ATF and ATM files from the ARENA2 directory, as well as the BIO.DAT, MAPSAVE.SAV and the RUMOR.DAT files, also located in the ARENA2 directory.
#* Run Daggerfall using DOS32A and load the savegame. If this doesn't work, see step 3
#* If this step did work, you must do this procedure from now on whenever you start the game from DOS, but you only need to delete the ATF and ATM files.
#* You can write a small shell program (BAT-file) which does this task for you and starts the game afterwards, for example:   @ECHO OFF del ARENA2\*.AMF del ARENA2\*.ATF 
#If you have tried step 2 and you couldn't load the savegame, run Daggerfall again using DOS32A, this time without deleting any files.
#If you used the workaround mentioned in step 2 for some time and you get corrupted savegames again, you must not delete the files listed in step 2 anymore. Just start the game using DOS32A and load the savegame as you would normally do.

If none of these steps worked, the savegame is corrupted beyond any known workarounds. Use a savegame dated earlier than the corrupted one and use DOS32A from now on.
