If you have a disc image with audio tracks in bin/toc format, here's a guide to extract the data track to a plain iso file that you can mount with Toast etc. This process was tested in 9.2.2 but should work from 8.6 up (BinChunker requires CarbonLib). First, download the required files (Datafork Trimmer, BinChunker and a generic .cue file) from here.
Open the .toc file in a text editor and make a note of the size of the first (data) track (Fig.1). We need to trim the .bin file down to this size. For this we will use mathieudel's very own classic solution "Datafork Trimmer".
Run Datafork Trimmer and open the .bin file using the select button beside the Input field. Now click on the select button beside the Output field and click Save. It should now look like this (Fig.2). Go to the length box and replace the contents with the required filesize from the toc file. Once you have it looking like this (Fig.3) you can hit the Trim button and wait for it to finish processing.
Now we need to convert this from a raw image file to a plain iso. This is where BinChunker comes in. When you run it, it will ask you for a .cue and corresponding .bin file. Select the .cue file from the archive (Fig.4) and then the trimmed bin file. It will now begin converting the file to a .iso. Once this is completed we have a plain .iso file that can be mounted on the desktop or in emulators (Fig.5).
If you want to do this in OS X you can trim down the .bin file using dd from the terminal. Here's a sample command:
dd if=N4_11_93.bin bs=628165104 count=1 of=track1.bin
Once you've trimmed it, you can use this copy of binchunker (which should be compatible down to 10.2.x) from the terminal to convert to iso:
binchunker track1.bin track1.cue N4_11_93.iso
... I will make them myself but they won't exactly be "cool"
