Sorry if I missed a similar thread but how much is a Cubic Ninja cartridge worth right now without the case/manual? Mines is lost and I am trying to replace it. The prices online is insane! I am seen a minimal $45!
its that expensive because people want it for homebrew. technically, prices should go down right now, since ironhax and browserhax and a bunch of other haxes are back for recent firmwares again. but don't expect it to go any deeper than 30 bucks or so.
Yeah, if you download the old Ironfall while you still can (unless it's already been fixed by Nintendo), and as long as you carefully updated its payload every time you wanted to update your 3DS, you would never need CN.
CN is great for if you screw up, though, and didn't update Ironhax payload properly. With CN you never lose access.
As of right now though you'd be better off staying on max. 10.3 and downgrading once it becomes possible. Then you never have to worry about anything anymore.
