My new 65816 Computer, very proud!
I also found this Forth implementation that might work.

Ben's 6502 running with a 65816
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.

Starting a 65816 emulator in C#. I think this is going to be quite fun! So far: loading actual ROM binary, reading reset vector, jumping to and reading the first two bytes from that vector. (baby steps) I'll be able to dial this into my specific hardware config, which will be great.
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.

Starting something new in February... Step 1: buy stuff. (W65C816S build)
Unfortunately, Liara Forth is coded specifically for the w65c265sxb development board. I'm not sure how hard it would be to get it running on 816sxb. I was able to get it running in my py65816 simulation by changing the getc and putc addresses in the binary. Maybe something similar would work for you.

Simulating the 65C816 in py65
I still have a lot of testing to do and not all features of the 65C816 are working yet. You can test it out yourself and follow my progress at GitHub.
