Anyway, this is the Peer Pressure softmod I posted about earlier. It's pretty painless to install even if you have no modding experience and is compatible with all but the last few motherboard revisions. This guide also mentions other stuff worth installing, too: www.youtube.com/watch?v=G8ce...

That exploit is Peer Pressure from Grimdoomer, and its GitHub page lists what it needs: a 360, a mechanical hard drive and a USB stick.
If there's a 360 in your closet, check the motherboard revision first.

This was the exact kind of thing GrimDoomer was worried about happening and it's frustrating to see people in 360 Homebrew communities parading it around because it has plugin support
Figures something like PeerSlop would happen
An AI decompilation and recompilation of PeerPressure to add Dashlaunch plugin support
I already do not trust it from the name alone, but hearing what is is makes me not even wanna try it

for the record people HAVE gotten some dashlaunch plugins and stealth servers to work with the softmod, however it's not really recommended, as from my experience, it's not that stable, and could break at any time when grimdoomer updates peer pressure
there is a REASON it's unsupported
there is a REASON it's unsupported
people are being really annoying about the upcoming xbox 360 softmod not supporting dashlaunch plugins/stealth servers
more people need to understand that some things are not implemented purely because it's not within the scope of a project rather than out of malicious intent

i think the Free60 wiki is the only guide that has the correct distinction between Bad Update and ABadAvatar and that's that there is no distinction they're both based on the Bad Update exploit

As an extremely vocal FOSS user, I agree 100% with their reasoning.
Maybe in 5 years when things calm down, and the softmod is "feature complete" to their liking, then they could release the source.
