Trying to figure out how to make several Nintendo Gameboys communicate with each other in your game?
Use this handy piece of commercial grade source code written in assembly to handle it all for you.
This is a fully functioning example of two Gameboys communicating with each other over the serial cable.
The source code was originally written for a Gameboy title that was never published and rather than let the source code remain unused I thought that other people might benefit from it.
The .ZIP archive contains all the source code you need to be able to integrate multi-player in to your games.
I do not offer any kind of technical support with this software so please do not ask.
You should be aware that this software is copyrighted and the source code does belong to me but I am granting you a license to use it for free, in a commercial or non-commercial product.
If you distribute the .ZIP archive on your web site, or give a copy to someone else, please leave the license.txt file intact. Even if you, or they, do not read the license.txt file you and the other person are still bound by it if either of you use this software.
The license is more than fair, it just says you can’t sell this source code in source form or as part of an API or library but you can put it in to a product and sell the product and not owe me a penny (or cent.)
This is a legally binding document, so read it!
