Hi I want to set up ninjhax on my emunand. But I also want to cold boot my 2ds using ctrbootmanager. But my problem is, both ninjhax and ctrbootmanager needs "boot.3dsx". How I can set up ninjhax and ctrbootmanager? I'm a noob 

I alreay did it. I edited the menuhax payload using HxD , and renamed it haha
