The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.

Starting something new in February... Step 1: buy stuff. (W65C816S build)
I got my w65c265sxb board up and running with the help of the A Most Very Unofficial Guide to the W65C265SXB and Liara Forth. I found it very helpful to have a fully functioning program to start learning the 65816's new modes.
