Don't even "hexedit". Open the payload with a text editor like Notepad++ then look for "boot.3dsx" (not yourself, you'll get lost in the garbage you'll see, use the search function) and replace it with any name the same length.Thanks for your reply, how can i do that exactly?
I recommend editing menuhax's payload and not this cia's payload, because this cia's payload will have to be updated everytime you update your emuNAND, while your menuhax payload is more likely to never change.
Alternatively, you can just download lesshax's payload and replace your menuhax payload with that. It boots to "less.3dsx", so just have ctrbootmanager as less.3dsx and the HBL as boot.3dsx and you're set.
