I have a .BIN file but no .CUE?
.CUE can be made with just Notepad. A typical Playstation(One or 2) .CUE file looks like this:
FILE "image-name.BIN" BINARY
TRACK 1 MODE2/2352
INDEX 1 00:00:00
A typical PC CD-ROM .CUE looks like this:
FILE "image-name.BIN" BINARY
TRACK 01 MODE1/2352
INDEX 01 00:00:00
"image-name.BIN" being the name of the image file (IWDII.BIN, CIV3.BIN and so on...)
Notice the difference of the track mode - PC-ROMs being Mode 1, Playstations CDs Mode 2 and (Super)Video CDs are also MODE2/2352.
How do I make .BIN/.CUE files?
CDRWin or the BIN/CUE format is not ideal for distributing. BlindWrite suite and CloneCD perform a lot better in this purpose and can also handle various copy protections. Both of these softwares can also create .CUE files for increased compatibility
