Anyone used Primo DVD to copy CD-R?

[ADLER]

I have read through the posts, and haven't seen that anyone has used Primo DVD to copy onto CD-R.
Last night I copied Contra (I don't know if it works because I don't have my mod chip yet) onto CD-R following the exact methods given to use Primo DVD (for DVDs). It appeared to have worked, just curious if anyone else has tried it.
