Replacing the battery takes a couple minutes. Many of those carts are still running. The number of decent NES games that used battery saving can be counted on your hands, so to call it a LOT of pain might be exaggerating a little.

A "couple of minutes" for a confident, competent solderer, which excludes about 99% of the target market for this thing. (Here's how to do it, if anyone's curious: http://www.retronintendoreviews.com/nes-cartridge-battery-re...)

And while overall most NES games didn't use a battery, many of the most popular ones (many of the ones included in this thing, in fact) do need a working battery. Final Fantasy, both zeldas, startropics, tecmo bowl, crystallis, kirby's adventure...

If Crystalis has a battery-backed save system it's news to me. And I've beaten the game on the original hardware.

Crystalis absolutely has a save/continue system. You can see some guy demonstrating the save system in crystalis in this video, complete with save functionality: https://m.youtube.com/watch?v=73za3LHWzwk

Are you thinking of some other game?

Incredible. I owned the game for years, played it a lot, beat it once, and never noticed a way to save, so I assumed you couldn't. I even had the manual!

I think it's fair, Remember being 12?

Then again, when I was 12, my elders we're a very different set of folks.
