I have tried it on three Philips burners that all support SD2, all burned many SD2 games before, I only tried it on a CDRW though. Maybe that was the problem, although other SD2 games worked from CDRW. Anyway, I have got the CALiso release now which works fine. BTW 3 other CloneFXP isos of Sd2 titles are listed as NOT WORKING on isonews, so i figured it wasnt worth wasting any more time on it. Weird that it works for you though...then again SD2 is and remains a mystery. This was the only time an SD2 burn failed on my trusty Philips PCRW404.
Are you sure yours was the CloneFXP release and not the CALiso?
