Binflash version 1.52 has just been made available. This version adds support for the AD-7700H slimline drive and also adds basic flashing support for the Optiarc BluRay combo drives. This means that you can flash within the same series of firmwares like 1.00 to 1.03 or 1.08 but not to 1.10, 1.23 or 1.xy. Also dumping firmwares is not possible at the moment.
If anyone can get hold of an unencrypted Optiarc BluRay drive firmware, feel free to contact me.
