Hacking How long does the save battery generally last?

[turtleman]

And is it replacable by conventional means? (or do I have to desolder it like my old NES and SNES games)

This is most likely for the newest chipset model of the 3in1.

EDIT:oops! wrong forum, I thought I was in EZflash, uhh..can a mod move this for me?

kthxbye.
