GOOD BUT NOT PERFECT
Yup I did make working backup copies of The sims deluxe edition using both cloneCD and Ddump. But the bad thing is I have to use hide cd-r trick in order to play these backup cds with cd burner (liteon 32X). I live in US so I have to re-install again with woody's trick (change region to cananda before installing clone). However Burnatonce 0.91 beta cannot burn this image made by Ddump so I have to use Nero 5.5.9x. And this test was done in my old system. I'm still having problem running Sims deluxe in my new system with AIW 8500DV (see another post).
Thanks everyone for providind all info and make this work.
Edit Post. Burnatonce works with image made by Ddump just have to change "iso" to "bin" before burning.
