So well known that I've never heard of it. :o :bigsmile:
Nevermind. If it's a 2 sheep writer, try using alcohol with safedisc 1 datatype settings making sure you enable Ignore media type before trying to play from the back-up copy since your only reading device is a writer. If that doesn't work, try using safedisc 2 datatype settings. (Tip: experiment with a cdrw to avoid coasters.)
If neither works then you'll probably need to use some form of emulation. The easiest is to just use CloneCD with the default Game CD profile (or the safedisc 2 ignore profile that you can download from the profiles sticky on the CloneCD forum). A copy made in that way will work so long as CloneCD is installed on the system and hide cdr media is activated.
