It's a long time since I did this but I think either ISOBUSTER or CDMAGE will take a BIN file and allow you to extract the components. Look at a file called SYSTEM. That is a clear text file which will contain the word NTSC or PAL.

I've not thought too hard about this because I never come from ypur perspective - I know BEFORE I create a BIN file what it is! It MIGHT be possible to use the DOS DEBUG command on the BIN file (which is everything rolled up) and look for the words PAL and NTSC; hopefully one will appear but not both. CDRWin also has a facility for reading sectors. Or you could open the BIN file with WORDPAD and search for the string. Or maybe not - try it.
