burning serial uploader disc

[Matty B]

I'm having a nightmare trying to make a serial uploader disc to rip my own game's using a serial cable.I have the instruction's for making one from the link in the dreamrip readme file. I've managed so far to make a disc with the 3 second's of audio but then I have to make an iso9660 image and then replace the first 16 sector's with the ip.bin which I downloaded but how do I do this?? I can't seem to work it out. Any help would be great. CHEERS!!
