quote from Marty
Just to clarify some possible confusion - does the Stern CPU require the actual file to be unpacked from Winzip to enable the ROM update?

yes. I am running latest windows (just bought this computer 1 x week ago and it came loaded with software, but did not have winzip.

AMD told me to download the new gamecode file from the Stern site. Winzip not needed for that. But once downloaded to my computer, they told me to open winzip and convert file to a zipped or unzipped, whatever the term is etc, then, and only then will the USB stick be registered/seen by the ACDC game etc. I am not technical with computers but without the winzip conversion, it will not work in the pinball machine. does that make sense Marty. I think u know what i mean.
