Homebrew Random UltraMoon Crashes

[willprogresivo]

Hi. I've been playing a lot of Pokemon UltraMoon lately, and yesterday I started to get a "random" crash during the Charizard Fly PokeRide cutscene, which forces a reboot. But then it happened mid-trade on the GTS (altho I wasn't softbanned and the trade went thru anyway. After reboot I loaded up the game and the received pokemon from the trade was in my PC).

This is the error

I'm obviously using CFW, I hacked my N3DS back in November 2019, using https://3ds.hacks.guide/ and I had Luma 10.1. After getting the crash I updated to 10.2 from their github, but it didn't change anything. Any ideas what could it be? It's worked fine for the past 9 months. THere was no change to any software, update or anything, the crash just randomly started occuring as I was playing. Thanks!

Now it's also happening on battles, so this makes the game literally unplayable. Haven't checked other games yet, but I'm thinking this might be general.

Check if your SD card is fake, faulty, or dying.

1. Copy everything off the SD card to a computer.
2. Quadruple reformat.
3. Full Write + Verify the empty card in H2testw. Do not skip.
