I have to admit I wasn't aware of this rule. I wish I could remove it myself from my post, but I already read in another post on the forum that you couldn't edit a message after 15 min. So I'm sorry for this.
For sure it's quite difficult to find the "home" of Xbox tools and homebrews, things like an official website still running, or an official thread on a forum, with download links working. But I've been able to find what I was looking for so far, 10 years later, which isn't bad.
And you're right about the quoting, sorry for this too.
Anyway I've downloaded Hexen, I'm going to read the included text files and see if they make me confident to try something.
In the meantime would you be able to tell me in a few words why there are so many packages? Are they really different? Although Hexen looks to be the favorite on this forum.
