I haven't had the tools to compile mame set up in probably a year. But assuming I can get the tools updated to the point where I can compile bgfx shaders again, I'll post a hacked up version for you here.

Who knows, if I offend cgwg enough with the poor quality of the changes, he may even pop up to make some kind of official update.

Probably not though.
