Either way, No its not possible, and will not be for the next 5 or 10 years imho if people actually read the forums first, you literally can find that out in 5 seconds, people rather go on YouTube and believe that you can jtag xb1 or 360 with a USB drive, 95% of people use exploits to run piracy and leech while the other 5% actually developed homebrew and did the actual reverse engineering, if you look at 360 homebrew is virtually non existent, and 99% of homebrew on 360 is solely piracy and cheating driven, we don't hack consoles to pirate games as a goal, but piracy is gonna happen if anyone can run code on a console which idc about it, but why buy a console if you cannot even afford one game for, $60 is perfectly reasonable for a disc, I have no issue paying for it, I've been paying $60 for games since I had ps1, exploits are used so the consoles can be used as a devkit PC, the end goal is that it runs my own code, and not leeching someone else's and not to run roms, if you're a fan of Xbox, sony, or nintendo you really should really have the decency and respect support them, either way most people who pirate games have no idea how drm and security works, and what has to go into it to break it, they just expect they can put a file on a USB stick and load free games, this isn't 2003 anymore, companies know how smart hackers are and build the hardware as such..
Piracy is less likely on M$ and Sony products, as m$ and Sony sell their console at a loss, so its more affordable, unless you wanna pay $600-$900 at launch for a console, Ms and Sony make this cost up in service and software sells, while Nintendo makes profit, every console they sell they make money, and make money from services and games too, it doesn't hurt ninty as much since either way they made profit already
And all consoles previously listed are all prev gen, and again they weren't hacked to run illegal and pirate games initially, they all either ran Linux or a homebrew program.
