I was trying to run the atlantis demo from the Reality Centre and was
encountering the same problem. If you don't have an EFS system to switch to,
there is a script file which can patch the executable. Rob Jenkins posted
this in November. It is in the monthly-archives.

I can run the atlantis demo but I spews the following Warning continuously:

Performer Warning: pfESkyMode() Bad value 0 for mode 300

Also, it doesn't recognize Impact hardware, and even though it downloads the
textures it won't display them.

Any plans for an update of this demo for the newer hardware systems?

Happy hunting,
scott
