Saturn nrg/mp3

I d/l a saturn game called Thunderforce Gold Pack1, but sadly the iso track was ripped by NERO... how can I burn it right? I tried renaming it to ISO, but that failed... and my saturn behaves strange with that game.... sometimes it hangs to the copyight screen and others just says the disk is not suitable... I wasted many cd's for this
any ideas?
I couldn't have put it better myself.

Open the .nrg file with CDmage.

Right click on the data track in the 'image tracks' window and choose Extact tracks... .

You'll probably want to save it as Mode 1/2048. Save it where you want it and then burn the game as you would any iso/mp3 image.

That's the theory anyway. :
