If you used the boot config from the link, it will already have nosigchk added. And the patches for it are in patches.ini, not in a separate file. You should probably remove both SYSNAND entries though if you are using emuNAND, to avoid accidentally booting sysNAND and tainting your clean NAND.
If you are using that config you will need Atmosphere as well or it obviously won't work. As well as that you should replace the atmosphere\reboot_payload.bin file with the Hekate payload (rename it) so that rebooting will boot into Hekate rather than fusee-primary. And you could set one of the boot entries to autoboot, so you don't have to select it every time.
