I am using ver 12 of the arduino software. I unzipped the psx files in the the proper location as listed on the playground.

When I ran the example scetch I get these following errors.

I am just starting to understand the arduino and the hardware/software aspect of it. But I am unable to figure out whats going wrong. The errors listed appear deep in the source so I thought I would ask for help.
