The last few days I played Dungeon Keeper Gold via DOSBox on my Retropie.
Everything worked fine. But today I started the game and all of my savegames were gone. I took a look at the files via the Retropie File Manager and the files are still there in the Save folder but the game doesn't recognize them.

When I save again the new file is recognized and it is in the same folder as the others...

Maybe someone can help me access those savegames again or maybe knows what could have caused this so that it won't happen again?

Thanks!
