Ah, while I use the excellent cdrecord, I didn't know about libscg :)
I had been working with dvd+rw-booktype from dvd+rw-tools, so they
were at the top of my mind :)

Thanks! I haven't had a chance to try it yet, but I think there's a
minor bug with the conversion. The idea is to write the firwmare to
the drive starting at offset 0x20, and write the checksum in offsets
0x00 to 0x1f. (I suspect the order doesn't matter, but the Windows
flash utility was writing the firmware first, then checksum, so I
followed it).
Also, if it no longer requires transport.hxx, no need to say it does
in the comments :)
