As stated the model in question is LG GDR 8163B
I did download the firmware from here and it works a treat but I am wondering if there is a hacked version available.
I have the previous model LG drive and downloaded a patched firmware for that but that drive stopped working properly in that the disk wasn't being held in the mechanism when it was inserted.
I was wondering if I could flash firmware from the old drive to my current drive since their boards are almost identical internally.
