Game copy with .bin..doesn't work plz help

I got SC5 (repack version) and first I used fireburner to bin chuck it to ISO, then used winimage to make the files. Then I used Nero to burn the files, Mode1, Iso lv1
when it finished burning I can't run it on my dreamcast. I use utopia as a boot-disk. It would load, as the reindeer would change it's apperance, then nothing. Blank screen.

What had I done wrong?
1. Does using 2x matter? I burned MvC2 sucessfuly with 1x (cdi image)
2. Is it because of lso lv1? Some files has more that 8 characters
3. Is it Utopia? Does utopia suppot that or do I need another bootdisk?

Please help

U wont need another boot disc. I dont know about the 8 characters limit but if u have files' name more than 8 chars probably u need to change the setting so can support more than 8 chars. Also, what I do is try to burn the 1ST_READ.BIN as the last file..so in nero, try to set all files on high/medium and 1ST_READ.BIN as low so it will burn last.....
