First of all, most of what I say here is repeated in the video, so if you don't feel like reading, just watch the video.
So, in response to the thread I posted a while ago looking for someone to do an RGB mod on my N64, APE did the job. Initially, I had some problems; on the PVM I was using at home (the 13" PVM-1271Q), there was an interference pattern (a fuzzy bar) that appeared only when the audio was plugged in. We thought that the audio was interfering with the image. Perhaps it was, but as it turns out the interference pattern doesn't show up on my other PVM (the 20" PVM-20M2MDU). That means the problem I was having must have been due to either the monitor or the stereo amplifier I was using.
In any case, it's working properly now and it looks amazing. The image is incredibly clear and bright. One thing that I discovered that I didn't know before this mod is that the N64 uses a lot of antialiasing: not just of textures, but also of the edges of polygons. Not all edges of polygons are antialiased, but a lot of them are. It seems that the closer an object is, the more likely it is to be antialiased.
It's really not possible to convey how good it looks through pictures or videos, but it should give you a bit of an idea. Check out the photos and the video below. I hope you enjoy them!
