If you can get cdrdao installed on your system then that's the only way, none of the GUI's...MMB, Firestarter FX etc...will work.
The best way to cope with an audio/cue combo is to split the file with shntool or xACT. You have to remove all the lines in the cue before the one that begins "FILE", save the changes and then split.
It *is* possible to burn such a combo with Toast but it's a rather kludgy procedure. Change the extension from .wav to .bin and edit the cue (pre-FILE lines are no problem here) so the relevant line reads
CODE
FILE "MTB.bin"
rather than
CODE
FILE "MTB.wav" WAVE
.
You can now go to Toast's Copy tab, select Bin/Cue files from the option drawer and burn.
If the CD being copied had a pregap, you will end up with a copy, though it will be one sector longer than the original. If there was no pregap there will be a click comparable to a sector boundary error at the beginning of the CD so you need to engineer one by inserting a line thus:
CODE
PERFORMER "THe Marshall Tucker Band"
TITLE "The Marshall Tucker Band"
FILE "MTB.wav" WAVE
TRACK 01 AUDIO
TITLE "Take The Highway"
PERFORMER "THe Marshall Tucker Band"
INDEX 01 00:00:00
to:
CODE
PERFORMER "THe Marshall Tucker Band"
TITLE "The Marshall Tucker Band"
FILE "MTB.bin"
TRACK 01 AUDIO
TITLE "Take The Highway"
PERFORMER "THe Marshall Tucker Band"
INDEX 00 00:00:00
INDEX 01 00:00:10
Total kludge but you will preserve any INDEX 00 values, whose loss is the only downside of simply splitting the WAV instead.
