I know that it's possible to upgrade/downgrade OFW via ChoiDujourNX, BUT, is it possible for someone to SIDEGRADE to a different firmware, officially, that way they would still be able to play online? I got a buddy who's on 5.1.0 FW and was thinking about upgrading his FW so that he could play online. He's not really ready to get into CFW "YET", but I think that will eventually change after he gets bored of playing online etc. So I told him that he should at least wait and let me see if there was a way for him to sidegrade to 6.2.0 FW. I thought I remember seeing somewhere that one of the ways to do it was to find a game that required the firmware you wanted to be on, and then just use the game cartridge to update to that FW. But since I don't know of any games that require 6.2.0 FW and come with that FW on the cartridge, I'm wondering if there is another way that's possible?
