Dave2000 seems to be working quite hard on his Glide plugin for n64 emus. He updated his site with some news and a new screenshot showing the improvements. Here's what he says:
I've got textures working. There is no transparency or constant colors (like on mario), but the textures load correctly and map to the objects. The problem: when textures are clipped, there is a perspective warp (look, left side of screen). I'm working on fixing it right now. I'll post a new version after I implement blending modes.
