Hi there, I've had my N8 for quite some time, and it's working quite well. Recently I've bought a Retro Zapper from Retro Bit, which they claimed would work on both the original NES and FC. I'm using the Famicom AV btw, and it doesn't work when I'm playing games like Duck Hunt, Hogan's Alley through the N8. Does the N8 have compatibility issues with 3rd party controllers? Thanks!
