Back in the old days when Cubic Ninja was required to run HBC and Hanz didn't exist, this was a thing for users wanting free methods of emulation. But now a days we are awash in entrypoints. I suppose it's a nice novelty to have a new injector using the browser. Would be cool to see a return of the Pokemon injectors too. But Hanz and the save data homebrew (svdt I think it's called?) make that redundant as well.
