[YZF-R6]

I wish i knew more but this may help, I've heard that for copying Dreamcast games DiscJuggler version 2.xxx works better than 3.xxx, if everyone who is having problems is using version 3 that may explain it. Unfortunately I have not been able to verify this myself but you may want to try version 2 and see if it works. Also, i believe that the correct setting under the advanced tab is 'Mode 2'.

That is all I know, please do not message me for further info.

good luck.
