Same for me. I was in 6.2 and i update my firmware by ChoidujourNX to 9.0.
After the reboot, i can't launch Custom firmware. I've Nintendo error "2168-0002"
(my sysnand it's ok, i talk about my emunand)
@SylverReZ, I also heard one of the Prince of Persia games was so unfinished that it required the "24/7 online" drm so a puzzle could be done and the game could be finished. And that when the Ubisoft servers were closed the (cracked) game was impossible to finish or something like that
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
