How to burn a DC game, when no .CDI file is present?

[spiff]

I downloaded a game in .ace format and when I unpacked it I saw that there wasn't an image like .bin or .cdi, the files was just ripped from the cd and then packed.

I tried to burn the files with DJ, but it didn't work. Anyone know how to burn these files, should I open a new session, what mode, maybe CDRWIN is better?
