I read on another forum that they just cut that blue wire off and it works. Though I cannot verify, other than I checked a teardown of a working retail unit 2DS XL and noticed there is no blue wire in any of the 2DS XL working retail units. Only the demo/kiosk versions have the blue wire, think...
I like that games can be fixed after the fact, hate that it's being abused via beta tests... And DLC... I was a 7800 owner back in the day and loved Impossible Mission, turns out I couldn't beat it because it was actually impossible lol
