Hi Spike, I was just wondering where you’be been, and here you are!
On the PS3 Converter window, the ‘Merge new songs with exi’ box is checked, but it is greyed out.
You figured it out already, but to others’ benefit, I believe that when it is greyed out it is because the “songs.dta” file is not found by C3CONTools under the folder where it is supposed to be, which is the “Merged Songs” folder.
You are about to leave Rhythm Gaming World and access the external songs DB. While no song or file sold for commercially available videogames is hosted there and only fan generated content is allowed, Rhythm Gaming World has no direct control over the database and no files are hosted here. Alright, we had to made you aware of this, now you can visit the database!
