I have the german mac version of You don't know Jack 3 here and it has a Data track (HFS) and several Audio tracks. So far my images resulted in Data Track only images or in something that no tools (including the one that wrote it) could read.
I have an Intel Mac with El Captain, one Intel Mac with Snow Leopard and one G4 with Mac OS 9 and some early version of OS X.
Any ideas or even how tos?
