Are you referring to the RS1 songs in Rocksmith 2014? If the RocksmithToTab GUI does not pick them up during conversion, you can try the following:
Go to your Rocksmith 2014 installation directory (C:\Program Files (x86)\Steam\steamapps\common\Rocksmith2014) and locate the dlc subfolder.
In there, find the two files rs1compatibilitydisc_p.psarc and rs1compatibilitydlc_p.psarc (or similar). Drag and drop each of them onto the RocksmithToTab.exe (not the GUI version). That should convert all songs in those two files.
Output will be either in the dlc subfolder, or in the directory where your RocksmithToTab.exe is located.
Hello guys, anyone know how to fix this? It's not converting rs1 songs and I really need bass Pearl Jam - Black
Thank you
