Arduino 6502 Controller
The 6502ctl project is an Arduino controller for the 6502 CPU. The controller controls all 6502 pins, including the clock signal and interrupts, and simulates an address and data bus with attached memory and an output peripheral. The controller includes a clock-cycle debugger with disassembler. An assembler is also included with the project.

In plain words
Arduino 6502 Controller is a project that uses Arduino hardware to control and test a 6502 CPU. It manages all the CPU's pins, including clock and interrupt signals, and simulates memory and peripherals connected via address and data buses. The project includes tools for developers: a clock-cycle debugger with disassembler for analyzing CPU execution, and an assembler for writing 6502 code. It is intended for hobbyists and engineers working with 6502-based systems.

I wanted to polish the code a bit more before sharing (I especially dislike the self modifying code part), but the computer seems to have developed a hardware problem lately and it keeps crashing (bad RAM chip most likely), so I am sharing as is.
