Homebrew Question EmuMMC boot blackscreen

[desperateforhelp]

It worked. The whole issue seems to be a corruption of my emummc on the sd card. Wiped it and made a sd partition and the emummc on it. Now it's working again and I'm happy that my switch will now be safer because I have fat32 and partition. I tried extracting the games and saves from the old emummc but I didn't get it to work, either those are corrupted too or I'm not good enough at it. Not that bad because I have some checkpoint files from a week before and completely up to date ones for games I didn't play a longer time.

Thank you both for helping me.

This is a stretch as I'm replying 2 years later, but it seems I have the exact same issue you were having and this is the 2nd time it has happened to me. Was this a reoccurring issue for you too? Were you able to find a permanent fix? It seems somewhere down the line my emuMMC gets corrupted or something and whenever I get booted out (either by my switch dying or by choice) I am unable to get back into the emuMMC and am met with a perpetual black screen when booting while the sysnand and sysCFW work perfectly fine. Last time I was able to just reformat the emuMMC and redownload all my software but this is a pain to deal with every time my switch inevitably dies at some point. Some people suggest that it could be an SD problem but I've had no issues outside of this and I'd rather not spend money on a new SD on something that is not easily verifiable. Any insight?

Verify to see if the SD card is fake or not.
