C64

Project Description

An emulator for MOS 6510 CPU used in Commodore 64. This project contains no UI, only internal representation of the CPU written in C#. There are also an assembler and a disassembler. 

Goals

I wrote this only for learning purposes. There are no specific goals.

Learning insights

  • The strategy design pattern is used to avoid a long switch statement in file ExecutionContext.cs.

Solution structure

  • MOS6510 - the actual emulation engine
  • emuConsole - a console app for running some quick tests
  • Test6510 - a VS unit test project

Progress

The progress is visible in the file called Opcode.cs that lists all implemented opcodes. If you contribute, then please only add opcodes to this list that are implemented and tested. This ensures that that Opcode.cs file is up-to-date at all times and reflects the progress of the project.
