Quick Sega Saturn game case question

[Matt16]

Geralds right about the cases being crap but they can just be replaced if needed. PDS comes with a card outer case as well though which you are unlikely to be able to replace.

The battery was the worst idea for a backup system I can remember. It's used for system settings etc but also for your save games. So you take it out you lose all save data. I'd recommend buying a backup RAM cart which can also be used to save your games and not use the internal memory.
