Fake specular shader for a sphere?

I want to achieve a specular effect without a normal specular shader. So essentially I want the regular ball texture to roll around but also overlay a fake specular highlight that doesn't change with the orientation of the ball.

I anticipate this kind of effect will be a lot more processor friendly and doesn't require any special hardware (I'm developing on mobiles.)

I'm not very experienced with writing shaders so while I could combine two textures, I couldn't figure out how to make the second texture stationary.

Thank you!

you may be able to do it this way:

use a texture that matches the type of specular you want, now you just need to find a way to make it only project on to the ball and nothing else.
