HaloMods "Classic" Read-only Archive

I know there's a tutorial on this, but it was kinda confusing. I have all of my unmodded maps backed up and i'm ftp'd into my system looking at the maps. I've used ppf-o-matic to apply the ppf to my map but whenever i put the map back on it keeps showing up as the normal version of the map. After i use ppf-o-matic does it add the ppf to the map that you've selected to add it to? please help...

You mean this tutorial?
Try it again. It will work if done correctly.

Or, you can just open the map in DotHalo and apply the patch (still in DotHalo). Then you can sign, and FTP back over to your Xbox.

do you have to resign it?

Yes, and do this http://files.halomods.com/viewtopic.php?t=37383
