Today I successes to render NBG0! it's need much more time to make it playable. since speed is the biggest problem of SEGA Saturn emulation, my effort will be worth wile.

Yaba Sanshiro has the cloud save data function. If your local storage does not have save data, you can copy back them from cloud storage. You can also save your cheat code to the cloud storage.

I added below menu options to enable this idea.
