Most accurate NSF player? (and other game formats too)

I'm looking to start ripping songs from NSFs to MP3s again and I'd like to know what's the most accurate NSF player available? I'm also looking to do the same for other formats like GBS, HES, KSS, VGM (Genesis, Master System, Etc.) and several others. I've been primarily using Foobar2000 as my main music player and chiptune player thanks to the Game Emu Player plugin.

For NSFs, I usually recommend jsr's NSFLive 0.95, or Brad Smith's NSFPlay.
