well this is how a cue file of a normal bin file looks like:
FILE "C:\testing.bin" BINARY
TRACK 01 MODE1/2352
INDEX 01 00:00:00
another example:
FILE "C:\folder\test.bin" BINARY
TRACK 01 MODE1/2352
INDEX 01 00:00:00
remember the cue file to be in the same folder as the bin file.
for the same size of an Image, bin files are larger than iso files. personally i would prefer creating iso files rather than bin files.
