Ice Man is saying to use the forum search function. But the forum search doesn't work very good. I always use Google, with "site:forums.nesdev.com" in the search field, that's more useful.

Here's a recent thread about SNES battery backup:

You can find a write-up of the battery circuit that I use (the one detailed in the above forum link) on my website. It's crucial to get correct if you want your games to save longer than a few weeks at best. I've found a few repro boards online seemingly don't have this implemented for long battery life.
