It's a bit more complicated than that, but yes. Basically you use the toolkit to unpack the .dat,, then import the xml files from that into EOF in order to generate new .xml files for Rocksmith2014, then repack. But are you sure the .dat you want to play hasn't already been converted? Yes, I found some old Rocksmith .dat CDLC files that arent submitted yet for RS14 but I want to play them so much. Is there any tutorial for repacking it? Thanks for help btw
