By replacing tracks on the first Fury campaign grid I managed to load Pro Tozo and Corridon12 as Single race. Look in my album for pictures. Mallavol hangs on loading screen. I will try to change TitleID today so that it doesn't conflict with the ordinary HD Fury installation. I will gladly share pkg files for this as well but it requires Rebug firmware and reActPSN plugin for installation.
This is starting to get pretty crazy!
Head2Head is fully present in the code with working HUD just like in Pulse! Pic in a few minutes...
