I have only the stuff that's enabled by default. Try removing the sys-patch folder or something like that from the config folder on your SD card and reboot.
Once it reboots, open up the Tesla menu and select sys-patch and make sure that patching is enabled on sysMMC as well (it should be by default, anyway, but it doesn't hurt to check). Also, check under logs to see if everything is Patched (green or orange, it doesn't really matter).
The only other thing that comes to my mind is blocking the Nintendo servers with 90DNS or DNS MITM just in case that game tries to access the Internet (haven't played it so I don't really know much).
I'd backup the atmosphere and bootloader folder, delete them from the SD card and replace them with the fresh files from
Atmosphere's and
Hekate's respective repositories. You can use the latest versions just fine as they are backwards compatible. Also, make sure to update your
sys-patch [
1][
2] as well. Don't forget to update your fusee.bin payload as well. Hopefully, it'll boot once you do that. Nothing else I can suggest you to do, anyway.
