I have seen many suggestions around this. From the command line I have tried to use chunk, but have no .cue files for any of my .bins. I have tried OPL Manager as alternative is it seems like it allows you to convert .bin files to .iso without the need for a .cue file. However, this is not working as I get a No save selected error. Why am I getting this error? I would prefer to do this conversion over the command line to complete the conversions in bulk if I can get OPL working that will be a good first step.
