How can I convert dreamcast nrg file to cdi?

[bshi02]

I have download below link of NesterDC emulator with roms and just noticed that It is not cdi image file but nrg.

I want to run it on my G1-ATA moded dreamcast But I cannot make descrambled iso file with nrg image file..
I absolutely need cdi file which must contains IP.BIN in order to run it on my dreamcast.
Is there any workaround to convert dreamcast nrg image file to cdi?

Mount with daemon tools then rip with disc juggler

Thank you very much for your reply!
I successfully convert nrg image file to cdi with your recommendation(making use of daemon tools and disc juggler)
and extracted all of files including IP.bin with gdrom-explorer and executed "descramble.bat" in order to modify 1ST_READ.bin and finally execute create_iso.bat and it seems that this converted iso file works very well in retrodream.
