of816 VS py65816

I also found this Forth implementation that might work.

There are several Forth versions for the 65816 that I've found online. Some are specialized to specific hardware but can be modified. Michael Guidero's OF816 is designed to be easily ported to new systems. I got it running on my 65816 emulator without much problem. It handles banked memory and uses a good subset of 65816 features.

One issue I had when I was finishing up my emulator was finding substantial programs to test that weren't designed for a particular architecture. I'm focused mainly on text-based programs, so it might not be as interesting for your emulation, but OF816, by Michael Guidero, is a larger program designed to be easily ported to new 65816-based systems. Here's my fork of it for my py65816 emulator as another example of porting it to an emulator. If you don't want to bother creating your own port or creating a binary, here's one with I/O mapped to 7FC0 and 7FE0 respectively. Load it at $8000 and reset to start. It uses bank 0 and bank 1 so you need to have at least those modeled.

That's how I learned the 65816 and Python at the same time. Here's my 65816 enhancement to py65. I took longer than I thought it would (mostly writing the tests to validate the emulation).

I found some alternative tools, but really wanted to continue using what I was familiar with, so that took some programming work as I couldn't find any options for my current tools. I've already written about my work on a py65 based 65816 emulator. I've refined it a bit and created a version that doesn't require modifications to py65. It's available on my py65816 GitHub. With that down, I only needed a 65816 listing file.
