I can confirm, as I reported elsewhere on this forum, that this file works correctly on MDD FW800 with Sonnet MDX dual 1.8 and OS 9. It's a very speedy arrangement. I really think it would be helpful to get this file added into the Universal 9.2.2 disc image, at least in another folder with a SimpleText note about it. I had to attach my boot drive to another computer in order to work around the default version causing an unavoidable freeze, not to mention a separate headache related to the base ATI drivers not being up to date enough while also having the Rage driver present by default causing yet another unexpected freeze with my Radeon card.
It would be nice to know what's really going on inside these CPU Plugin files. I'm curious if there would be anything to gain from deciphering what was patched and applying that to a later version of the file. Does anyone here know how to disassemble and interpret that file?
