Nitro Ground Shaker Multiball ROM

I recently stumbled across this page: which references a patched rom for NGS that adds a 2x PF multball. Anyone know where I might find this rom? My Google-Fu has let me down.

Clay has it in the Michigan pinball museum

I am also interested in this. If anyone has a link to the mod and rom, please post.

I would be very interested in this ROM as well. I have looked around and can’t seem to find any mention of it besides this forum topic…
