PSX Cue file maker script

[A Former User]

Hello to all,

I have created a python script to automate the making of the .cue files for all the .bin files found in the psx roms path.

If the script already finds a .cue file for those .bin files, it doesn't make the .cue file again.

I hope this script will be useful for you.

	myFilenameWithoutPath = os.path.basename(aFilename)
	
	if aTrackNumber == 1:
		myOutputText = "FILE \"{filename}\" BINARY\nTRACK {track:02d} MODE1/2352\nINDEX {track:02d} 00:00:00"\
			.format(filename = myFilenameWithoutPath, track = aTrackNumber)
	else:
		myOutputText = "\nTRACK \"{filename}\" BINARY\nTRACK {track:02d} AUDIO\nINDEX 00 00:00:00\nINDEX 01 00:02:00"\
			.format(filename = myFilenameWithoutPath, track = aTrackNumber)
	
	try:

@juanzt that cool. I have also found that just changing .bin to .iso works on psx emulators. Doesn’t seem to effect anything unless a game uses CDDA. It just won’t play the cdda.
