I was stunned that so much worked, and worked better, when we started loading scePsmf library from disk instead of HLE:ing it.

However, now we've found the first case of a game that breaks, thanks to a user report - Dragon's Lair (PSN). Presumably the underlying sceMpeg implementation is somehow not accurate enough for the real scePsmf to function atop it, for some kind of edge case.

For 1.19.1, I'm just gonna force it back to how it was for this game (NPUH-10105 and NPEH-00122), but needs investigation later.

Hopefully there are not too many more cases of this..
