By now.baten can only be played with RVL-mios-v10.wad on DVD.
The DM has problem with saving.it takes only 2~3 seconds to save,and gets corrupted save file.With RVL-mios-v10.wad,it takes about 5 seconds to save,and that save file is good,even DM can load the save file.but still can't get to save correctly.
So,wait for the new DM to play baten on HDD,or play it on DVD.(Both memory card required)
Agreed. I went back to using the discs as there are no issues with that. If you don't want to. Use your game discs make backups of them and use neogamma. There are instructions on how to create a multi disc backup. If you search google you'll find it.
