Summary	09470: indigo_r4400: Black screen
Description	This system is marked as working. The other system in this driver, indigo_r4000, starts up and shows a screen. I don't know if it actually boots as there's no software list and I don't have a hard drive image for it.
Steps To Reproduce	>mame indigo_r4400 Black screen. Tested on 0.277, same issue. System does not exist in 0.254 . Therefore I don't know if it ever worked.
