Here's a video showing the track "Straight Bit" from my chiptune pack Chip-Hop, playing on a ROM in the NES emulator Mesen:

I'd like to upload the rest of the tracks as well but the FamiStudio visualizer is quite basic. It would be awesome to have a dynamic visualizer ROM but I'm not even sure if that is possible (i.e. can the music events be read during runtime? I have no idea...maybe I should learn some NES programming...). So for now its just gonna be volume bars...
