Would anyone be interested in working on a WonderSwan emulator?
OSwan, which is generally considered to be the best PC WonderSwan emulator, is open source! It's already been ported to Mac and a handful of other platforms. I couldn't really contribute with coding at all, but I'd be more than happy to make graphics!
I realize this is a pitiful request, for an obscure handheld no less... but this is a project I'd love to see happen, and I'd help in any way that I could.
