Actually when you make a hybrid cd there is in fact two or more partitions. For instantce you can make a hybrid cd that has a mac partition (hfs_) and a windows partition (fat_) . How do you think cds such as Diablo can work both on widows and mac but only show files for the correct operating system. O and how would one exactly make a bin/cue file, I was personally thinking using toast to copy the root of the cd bit for bit so when dosbox loads the cd it will actually load both parts of the cd.
