I've made images of SNES-station and PGEN with 31 character filenames which work great, however, CDGen won't make DVDs, and Sony's DVD Generator truncates filenames to 8+3. I'm just trying to burn an MP3 player and want to be able to recognize the filenames.
Nevermind, it works fine, directories are 8.3 and files are 31, my mistake.
However, IML2ISO won't work. If I open the IML it complains about no system.cnf (I have one), and if I open the IMS, it comes up with volume ID 'UUUUUUU' (I entered SLUS-random numbers), and exits with no ISO.
