Beggar Prince, quick question

[bartre]

has anyone tried this game on a model 3 genny?
i just popped about an hour and a half onto it, only to find that it's not saving.
i know that some copies won't work on say an x'eye, but i've heard nothing about the model 3.
should i open up my cart and see if there's a battery i can change, or should i try a new genesis?

If you have access to a different Genesis I'd try that first.
