Here is the answer from the person who shared the file:

Sounds like a graphics plugin issue. Wipeout 64 has an oddball one, so some plugins may not support it or may require an entry added to an .ini file to know which one to use. Easiest thing would be to just try a different plugin.

I haven't used emulators for a while now, so you probably want to ask somebody attached to one of those projects for more specific help.
