NES games use CR2032 batteries as well. I'd also venture to guess that the vast majority of Pokemon Gold batteries still work as well. The Pokemon games in general do seem to have a higher rate of death that the average cart, though, but that can easily be pinned on the fact that they're played so dang much that the batteries wear out.
