A bit has happened since v1.3, mostly improvements to the GameCube version (Cube64), and some performance and stability improvements for all. I'd consider Cube64 more playable than any previous release to date for the GameCube, including the "Exp" (8MB RDRAM) builds.
Edit: Re-uploaded after the initial upload to fix a save states issue on Wii. If you've already downloaded it, grab it again.
