OK, thanks, somehow missed My Games, but now have the GC DA folder, and the saves are there. However, DA apparently overwrites saves in such a way that you only have saves of the latest game, plus a save called "endgame save". You do not have saves from previously played games so that you can have more than one game going at the same time. Anybody know if this is correct, or is there a way to save a half-finished game, start another one and save it, and have both available when you want to play again?
Thanks.
You have to do it manually, but it's pretty easy. As any point at all, go to load/save, and change the name at the top. Make it something descriptive of the game you're playing. Push save.
The autosaves, quicksave, and even endgame save will overwrite each time, but uniquely-named saves will not.
