Creating a multisession disc image with mixed content using the command line

[Zhelkus]

Hello, wonderful community. As of the past week, I've been trying to find a way to release a patch for a game but I've been having problems creating the dummy image.

Basically what I want to do is create an image file where only the audio track is present. To do that, I need to create a mixed content session with one data track (I've been sticking in a text file to at least put something in there) and one audio track (which is what I've been wanting to add).

However, I'm having difficulty in locating a command line tool that will create this mixed content image. I know that I can do it perfectly with any burning program, I just wanted to create an automated process through a batch file. :p

This is more or less what I want to do:
@echo off
"neroAacdec.exe" -if "Track 02.mp4" -of "Track 02.wav"
del "Track 02.mp4"
echo.
;this is where I'd like to run the CD image creator program
echo Convert finished. Load the the cue cheet on Daemon Tools and play the game.
echo.
pause

Any help, please? :(

Why commandline out of curiosity? :D Nero Express and Nero Burning ROM does this I believe...... CDBurnerXP Pro might too, though I don't use it.

Well, it's to release a patch for a game. Instead of having a wopping 500MB disc image, you only have 50MB, and when you download the patch you'll only have to download more or less 5MB. Pretty nifty, wouldn't you say? Know anybody that knows? Sorry for the redundance.

Only thing I know of that might make things easier is NSIS's patching functionality. Try that and see what you get. :)
