[UPDATED GUIDE] New Superuser version breaks Chainfire 3D - guide updated to show you how to fix it!

Trust me, you want this on your Android handset

So a few of you may have noticed a certain "Tegra-only" game release on the Market in the last few days - the utterly epic Shadowgun. If you're like me your first thought would have been "I wonder if I can play that on my non-Tegra device with Chainfire 3D?" If you tried to get it you may have run into a problem Chainfire 3D appears to have completely stopped working. Motivated by the need to get it working again, so I could enjoy me some Shadowgun on my Galaxy S II, I spent some time troubleshooting the problem today. I can happily report that I seem to have cracked the problem, and another editor has verified my fix works (he is currently missing, presumed fragging mutants in Shadowgun on his SGSII).

If Chainfire 3D is no longer working, or possibly never worked for you, read on to find the solution!
