Difficult to make a proper corresponding .CUE from just a .BIN.
.CUE’s should look like the following for example:

FILE "Crash Bandicoot 3 - Warped (SCES-01420).bin" BINARY
  TRACK 01 MODE2/2352
    INDEX 01 00:00:00
  REM LEAD-OUT 32:34:12

which instruct the software as to the layout of the disc image, number of tracks, where the tracks live, how long they are, how to read it.
