To everyone that's been having issues booting certain games, updates or DLC:
Please, make sure you know if you are using either fusee-primary or fusee-secondary, this is important to determine whether one set could be wrong, or both.
Once you know which one you are using, make a fresh install of Atmosphere, and then start using one set of patches. For example:
0) First off, try changing your payload. If you are using primary, try booting secondary, and viceversa, then try the games again. If they fail in the same way, then continue.
1) Be ABSOLUTELY sure you know if you're using primary or secondary. You can tell which one you're booting from the hekate_ipl.ini or from the payload you send to the Switch.
2) Make a fresh install of Atmosphere on your SD.
3) Download one of these three set of patches, depending on if you're using primary or secondary:
4) Once you select ONLY ONE of those packs, and copy them over to your SD.
5) Boot your Switch, test the faulty games and see if they work.
6) If they work, great! If not, repeat steps 2-6, but changing the sigpatches pack to the next one.
If your games work under a certain pack and/or payload type (primary vs. secondary), be sure to let us know, so we can start pinpointing the issue.
