Z-Net I:

Z-Net I is a program (Windows) that acts as a central hub and launch pad for people wanting to play the Super Nintendo emulator ZSNES online with friends or strangers.

With it you can play popular SNES versus games such as:

  • Super Mario Kart
  • Street Fighter II
  • Gundam Wing - Endless Duel
  • Dragon Ball Z - Hyper Dimension
  • Mortal Kombat
  • Killer Instinct

Co-ops such as:

  • Secret of Mana
  • Seiken Densetsu 3
  • Contra III

Or Classics such as:

  • Super Mario World
  • Super Mario All-Stars

Installation is quick, and setup for the program itself is easy. For ZSNES netplay itself however, you need to allow access through your firewall or router. To do that you can use this router guide to help forward port 7845. You should also forward port 4000 while you're at it.

Before using, read and understand the rules here.

NOTICE: Development of Z-Net I is officially done. The project will no longer be updated.
