Wonderswan tech

[Doomulation]

I was wondering if anyone had any wonderswan tech info.
I need to know how the input works. I know it reads port $B5, but the result of the returned bits does not match between the documentation and the source (oswan).

So I'm pretty stuck here. I want to add support for the Y-pad of the wonderswan (which is undocumented), but until I know how it actually reads the normal keys, it might be pretty hard.

Anyone has any info, please do share.
This would be so much easier if I knew how the returned bits are.
PS/ Zophar's tech info does not tell this. It, too, is incomplete, I've already looked there.

i know dox was doing a lot of ws emulation... his site is http://cygne.emuunlim.com/ and he has a documentation section on the side
maybe he'll even answer an email...

Yes perhaps mail if I can get a hold of it. But that documentation is even older than the one of zophar, so I'm afraid it won't help.

Oswan was as far as I remember based on the source code of dox's Cygne and Cygne definatly supports Y1-4 (ex. Digimon Card Game WSC)...

Yes, it all cleared up when contacting dox. A little confusing at first, but now I get it.
