YMF288-M Datasheet / .lbr file

Hi all,
I think I need to get out more, or at least find something else to play with.

After much Googling, which I seem to be rubbish at, I've come up blank for the:
Yamaha YMF288-M datasheet, also an Eagle .lbr would be nice!

Anybody out there better at Googling than me?

Thanks in advice.

Check here, in particular this and that. Happy google translate
Not much else came up. Maybe it's register-compatible to some other documented chip.

Thank you!
