Cannot play PS2 emulator

[Ratatapa]

Hi, downloaded the PS2 emulator for mac using this guide

http://pcsx2mac.net/guide/

The emulator loads OK but when I click load bios or load an ISO (I have the original game at home)

I receive this error

Need to download a separate Bios or what?

My guess is that it is an incompatibility with Lion since it was written with Snow Leopard and Leopard in mind. You are probably better off posting this on a gaming forum.
