When he gets the source, then it could be made compatible with the latest firmware. But this is very very unlikely. I mean, this thread is from 2021 and it's still just compatible 'till 11.0.0. Where's your dude now, huh?
And by the way, I never said it is impossible. For real, the first 9 pages are full with...nothing? Just random posts with code and random uploaded payloads on mega. That's fishy and everyone should know that payloads from untrustworthy sources shouldn't be executed because of the high risk to turn your console into an expensive paperweight. I'm not the only one who thinks exactly like this.
Okay, in my defense, a few posts of mine are not nice. I realized that. But still...that doesn't change my opinion about the beginning of this thread.
