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.

  3 17 0.0 Assembly

  Portable 32-bit Forth for the 65C816.

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.
