A simple, but effective, emulator for the MOS Technology 6502 8-bit processor. This processor was featured in many famous machines, including (but not limited to) the: Apple I, Apple II, Atari 2600, Atari 5200, BBC Micro, Commodore 64, Nintendo Family Computer (Famicon), Nintendo Entertainment System (NES), TurboGrafx-16, and many more. Launched in 1975, it remained in usage for decades, and has since cemented itself as legendary.
Writting this emulator was a passion-project for me. I started it with the motivation of potentially using this in a full NES emulator. Additionally, I wanted to test my C++ knowledge and learn more about 8-bit systems and how embedded hardware used to work.
For the code-layout, I wanted to do a more "forward-thinking" way of building my classes. It should resemble a compartmentalized version of the physical hardware with the bus, memory, cpu, and program aspects all being separate classes. Additionally, the bus and memory classes implement a abstract base class (IODevice) so that future work can expand and replace the basic systems I have written here, seamlessly.
Since this is a toy/hobby project, it features a main.cpp file to run the emulation.
But nothing is stopping someone from compiling it as a library (static or dynamic) and
using it that way.
The only dependency should be a C++17 capable compiler with the standard library (STD) available.
This was created with Microsoft Visual Studio 2019, so opening the solution file
mos6502.sln should take care of everything for you and you can build/run from there.
In the MSVS project, the include/ folder is in the search path, so the CPP files
do not explicitly specify the folder locations.
