Everybody here loves to see releases and effort on the scene.
Myself, I say go for it.
The project is for your satisfaction. If you will have fun doing it and you think it will be rewarding, go for it. I'll use it, and so would many others. Accuracy and playability are beloved by us here. I use your snes emu constantly, and FBL too. They're high quality, very professional; and I'm sure this one would be a wonderful addition to the xbox scene.
And yes, such projects are also about giving something to the scene and showing your work and contributions. And I'm positive you'd have a long page of deserved thank yous for your welcomed work!
And I did like the idea of helping the surreal ce effort. But I know that's off topic.
