essentially apps have checks each time you launch them to see if you should be able to or not sig patches bypass this

Patches signature checks.

So with this patch,

Apps like those games I purchase from eshop? Can I say that those NSP files I install have sig patches that bypass the check so that the firmware "thinks" I bought em and so enables the launch?

Thanks for the explanation.

This is untrue. The nsp files you are downloading and installing outside of the eshop aren't signed by Nintendo to run on your switch. They have a signature that is invalid. In normal stock firmware your switch will detect this and prevent them from running. Currently there is no way to modify nsp's to "trick your console into thinking you have permission".

Instead, custom firmwares can disable the switch from verifying theses signatures in the first place. This is what sig patching is.
