I received this email last night. Oddly, I can't find a Saturn memory card anywhere! Can someone lend an assist?

Could you please take a moment to assist me?
I recently purchased a Sega Saturn Memory Card (8 MB) for my son Tony's system.
How can he save game levels or scores to it?
He is Autistic (if you know what that is) and I want to help him save the
levels he has attained after hours of play.
There were no instructions with the cartridge, but we did see a "Memory
Management" console pop up. However I am not
sure how to use it and that is why I am seeking any help we can get.

If you are not familiar with the use of the memory card but know of someone or
somewhere that is, please tell us?

Thank You very much for your time in reading and hopefully responding to our
request!!
