No f*cking way man. DO NOT USE anything but CDRWIN. All other formats are well known, but you must not have heard, to screw up NEC images. If you get an iso+mp3 rip of ANY game, chances are someone screwed it up. But for NEC games it's CDRWIN only, if you want to get best images. Seriously, please, do yourself a favor, just use CDRWIN for about anything, but especially NEC games if yer gonna back up yer originals.
Sorry if i come across as harsh, or bold, but i have had to deal with so many crap rips made from anything other than CDRWIN for NEC images, and a few other systems as well.
