In this post, I’m going to describe some currently in progress work that I’m doing while I attempt to port the NES game Double Dragon II: The Revenge to the SNES.

In this post, I’m going to go more in-depth into how I convert the various bits of an NES game to be compatible with the SNES. This post will be a high level of some of the more straightforward bits. Later parts will dig into specifics and focus on a few single problems that I run into while porting the games.

Over the course of porting several NES games, it became apparent that I would be solving the same problem multiple times. And, because I’m lazy, I didn’t want to remember how I did those problems. For this reason I’ve created a template that has all the base pieces that I need for porting an NES game. This blog post will go through the pieces at a high level, and talk about where they’re used and why I’ve set them up the way that I have.

This blog is going to go over the process I use to port NES games to the Super Nintendo. Something to keep in mind while we go through this process: I’m by no means an expert on all these things. But I do know what’s worked for me. If you have ideas on ways to improve it, I’d love to hear them! Please reach out to me on Twitter.
