Development Builds won't run on my system

[parallelepipeds]

Okay, downgraded Nvidia drivers to nvvidia 320.49 (pretty old drivers) and it's not graying out on me, but it just boots up to a black screen that sits there... until I try to close it, at which point, it hangs, then finally shuts down. Again, the official dolphin release works for me, but none of the configurations for fixing SMG2 sound work for me on that build, so I'm curious to try a developer's build.
