Sorry for being so late. My motivation was burnt out, so I focused on getting back on track. I'm currently creating an emulator for MOS6502 using Python. It will take some time, but I appreciate your help.

So, I'll try using my own 8-bit CPU with a reset interrupt similar to the 6502.I'll try making a simple one with c.

During that time, I was feeling burnt out, so I watched YouTube videos from the Unix Archive to try to regain motivation and the motivation to build my own CPU and OS.

I'm really sorry for the delay

Let's talk about OS development

There's still some terrible code right now so I'm fixing it myself. Please wait for a while.

There may still be some strange parts, but I have defined it.This is a CPU made with custom instructions called mos6503, but I will improve the quality in various parts so that it is similar to mos6502.:CODE:


#include <stdio.h>
#include <stdlib.h>

// memory size(Test)
#define MEM_SIZE 0xFFFF ...

For now, this is all I can do as far as progress is concerned.
#define PC 0
int data_bus;

I created a user account for you all: Username: user1

I have published it. The folder is still empty, but if you would like to please: https://dcf7-119-173-26-116.ngrok-free.app

In order to learn how to use subversion, I will create and improve a simulator for learning how to make a mos6502 simulator with c.

Ok, I'm going to use sourceforge.net from now on, since it's easier to log in than github.

So why not provide it on another platform instead of github? What platform should we use? Any recommendations?

I'm sorry for saying something unnecessary yesterday, but I'm not familiar with Python, so I wrote a simulator that I didn't understand well, and it ended up being pointless. I'll try studying CPU again.
Accurate simulation of the 6502 is not an easy thing to do. It will take patience on your part ...
