N64

Ok, so I was interested in ripping some N64 models. So I download Lemmy's plugin and save it in the plugin folder of 1964. Now, I open up 1964. I click Plugins, switch plugins, and then change the video plugin to Nemu64 Grapics (combine debug). I click O.K. and open up a rom, and in this example it's Super Smash Bros Original. Then a window pops up, saying something about debugging. When I click no, it forces me to click no like over 9000 times, and it doesn't seem to matter which option I pick. When at the original debug screen I click yes, a weird glitched up screen appears. My only question is help.
