# Soft 65C02



Soft65C02 is a suite of softwares dedicated to 65C02 machine code testing and debugging. It is composed of 3 parts:



 * soft65C02_lib: a Rust library to simulate a 65C02 processor you can use in your own developments.

 * soft65C02_tester: a CLI tool to run automated tests against 65C02 machine code.

 * soft65C02_studio: (yet to develop) a CLI tool to run, debug machine code and create tests scripts.



If you want to use the old CLI tool, the last working version is e7e6615.



This is a pet project so if you are interested into real world software

regarding this processor, I suggest you have a look

### Why would you write another simulator for the 65C02?



I started this project in 2020 to learn the [Rust

language](https://www.rust-lang.org/) and … the 65C02. It has been a real

pleasure to code in the Rust programming language, guys & girls, you have

created awesome tools.



### The Rust language OK, but why the 6502 and not a modern processor?



Because the 6502 comes from an age where processors were built by humans for

humans. So the 6502 is a very good way to learn how processors work and are

programmed. Plus, the 65C02 is cool.



It's all [Ben

Eater](https://www.youtube.com/watch?v=LnzuMJLZRdU)'s fault by the way.



### What's the actual state of this development?



The library is supposed to be wire to wire compatible with a real 65C02. The

first version of this software (2020 → 2024) was a CLI against the library but

if this was a good first step it was not testable enough for evolving. In 2024 I

took advantage of free time to split the project in a Rust workspace to dig more

in GUI part. I rewrote the Tester with parser tests this time. The Studio is

yet to write.
