Is there a plan for GBA online?

Kirby & The Amazing Mirror The Legend of Zelda: A Link to the Past and Four Swords Advance Mario Kart Super Circuit

It's planned in the future, most likely when all of the more pressing GBA hardware is emulated. Currently that means finishing up Play-Yan support (to play real audio/video files), getting the Campho Advance fully working (real-time video chats), and potentially another project after that.

It's still on my TODO list, but keep in mind this list is still quite large.
