Just get a regular jtag/rgh dual nands are a pain the ass..

Liability wrote Yes, you would have to program it yourself. I would not recommend getting a dual nand due to the fact that if you host on the glitched side and get banned, the retail side gets banned as well and you can not unban it.

Unless you use a different KV on the glitch side than the retail side...

Yes you would have to update the demon to 1.04 firmware using demon toolbox and then flash your hacked image onto the demon and program the coolrunner with the corresponding timing file in jrunner, just select jasper and check the demon installed checkbox and you should be good to go.
