No. For all intents and purposes, you can barely play on that emulator - the hardware is not strong enough to pull off decent emulation. It was just a tech demo to show off that "it can be done", I don't think the creator ever had any intention to optimize it to playable levels, simply because it "cannot be done given the hardware limitations". That, and WFC actually checks if you're "logging" on with a real DS or not - it has been since the DeSmuME team developed its online plugin (which was subsequently blocked).
