Like the topic says I'm currently uploading a playthrough video of Rockman 2. What separates this playthrough video from other playthrough videos is that I captured this video from the new version of my rgb / s-video av famicom:
This recording was recoded from a real system that runs on all nintendo hardware. The audio and video circuits are custom (obviously). The stereo sound and video circuit are provided by a custom av famicom kit I ordered from japan and they're quite superior to any other circuits / setups I found. I also upgraded the video encoder on this kit giving it an even sharper video image and slightly better colour encoding.
I'm uploading the video right now (it's going to take a while it's about 1.1 gigs) so I'll post it when it's done. Here's some screenshots taken from the filtration process I used to make the captured video look as good as how the picture looks on my tv:
