This is most likely an issue with the USB GD-ROM device, not with the disc image.
Disc image boots and is playable in both latest Demul and the quite older NullDC (which are the 2 emulators I have up and running right now).
As per TOSEC rules for verified images, it is also dumped twice, by 2 different dumpers and from different discs.
I would suggest bringing the issue to the attention of whoever makes the USB GD-ROM device, he may like to investigate.
