I suppose it won’t be too surprising if this doesn’t work out. I think I’ve seen a half dozen attempts on myspleen of people ripping it to MKV (just a single crawl version), each stating “okay, this is finally the one to get it right”, only to be deleted and soon replaced with another attempt. Not sure if anyone has actually nailed it yet, and they’ve got their usual error of too many users online.

I’ve had nothing but success watching the actual disc and ISO image for 1.6. But it seems there’s something funky enough with its construction that the standard tools meant to deal with commercial discs, even branching ones, aren’t quite configured for this. As far as I know, this and the Despecialized 2.6 disc I built (thanks to Williarob’s enormous help) are the only two “homebrew” blu-ray discs in existence with seamless branching. Of course, I could be mistaken.
