Simple Instructions on how to get it working:
---------------------------------------------
1.) Go to Netplay -> Internet
2.) Decide who will be the server and who will be the client (Neither
has the gameplay advantage since ZSNESw treats both the same
after a connection is established)
3.) If you're the server, send the IP that's shown to your friend (eg.
through any chat program (ICQ, AIM, IRC, etc.)). Then click on
'Start Server'.
4.) If you're the client, type in the IP address that your friend has
given you and then click on 'Connect to Server'
5.) Chat with your friend on what game to play
6.) Once decided, make sure that the filename on both sides are the same
and that the load window points to the directory where the filename is
at
7.) Load the game
8.) Have fun! (If it worked)
9.) If it said 'Checksum Mismatch', then try unzipping the file if it is a
.ZIP file. If not, then both sides have a different version of that
ROM (eg. One side has the Japanese version while the other has the
English or both versions are English, but are different version releases
of the same game).
10.) If you want to chat in-game, press 'T' and type in your line.
You can change this key in the Misc -> Game Keys options from the GUI.
Getting the IP Address:
-----------------------
The IP address should be displayed on the connection window. The person
being the client has to somehow tell the person who is the server his
own IP address in order to connect. However, if your system has multiple
IP addresses, the one on the connection window probably isn't the correct
one. In this case, you can either refer to winipcfg (go to the Windows
Start Button -> Run, then type in winipcfg and press enter) or if you're
using mIRC, just type /dns <nick>.
Connecting:
-----------
When you're ready, select Internet from the Netplay menu.
If you are the server, just click on 'Start Server' and wait for the client
to connect.
If you are the client, and after obtaining the IP of your friend
(your friend has to send you his IP if you cannot figure out his IP on
your own), type in the IP into the space provided and then click on
'Connect to Server'. Once you click on it, your system may look as if
it's frozen, but it actually isn't. You just have to wait for a bit
until it either connects or fails to connect.
If it failed to connect, then check to make sure that the IP you entered
is correct and that you are properly connected to the net.
If the client says 'Found Client' and nothing else happens, chances are
that your net connection does not support UDP. If this is the case, then
both sides would need to deselect 'Allow UDP Connection'. However, it
is strongly recommended that you use this option if it is possible since
it is much faster than without UDP.
Loading a Game:
---------------
Once successfully connected, the chat window should open up. From there,
you can load a game like how you normally load a game. But in order to
load a game, both sides have to have their load window pointing to the
directory where the game is located and also have to have the filename
the same on both sides. Only one side has to load the game. After
that, the other side will automatically load the game without the user's
interaction. If an error pops up saying 'rom data mismatch', then
it means that either side have a different version of the rom. This
error sometimes happen on zip files even when both files are the same,
so it is recommended that you unzip the games and try again if this
error occurs.
Configuring the Options in the chat window:
-------------------------------------------
The default settings are recommended.
However, if your computer is slower than 266mhz, then it is
recommended that both sides play with back buffer disabled.
However, disabling this would degrade controller response.
You can increase the latency value if the average ping time between
both connections is high (you can tell if the gameplay runs too
jerky).
