Emulator Problem: Having a hard time getting Mupen64plus started.

Okay, so I did everything that the mupen64 website told me to do and even got the "mupenrocket" thing and it shows up fine. The problem is that I can't get the roms to show up on the startup page. I think it's because everytime I try to double click a newly downloaded game file, my computer just creates a new .zip file.

I'm currently using a macbook pro OSX 10.6.7

I just want to play some zelda since my N64 isn't working. I'm sure everyone that has stumbled upon the glory that is zelda will understand.

thanks, mcnutsackzach
