i installed the gateway exploit with a SCDS2, and now i want to play pokemon black 2 retail cartridge. when i go to classic mode from gateway mode it just stays on a black screen after pressing??
It's encrypted with the new 6.X KeyY (as I understand it) and EmuNAND uses the old 4.X KeyY, so it can't read Pokébank or the new updated YouTube app.
If you aren't confident at soldering I would recommend you try find someone to do it, I know you risk loosing your 3ds but if you do your research and find someone reputable you should be fine, don't just send it to the person doing it for the cheapest price with no proof or history of their work.
I have seen quite a few people screwing up their 3ds because they decided to try something themselves when they didn't have the required skill, so it's either risk screwing your 3ds or risk loosing it......either way you have to take a gamble
