This is a simple attempt to create an emulator for the Nintendo Emulator System (NES) using the dotnet ecosystem, fueled by my passion for computers, love for speedrunning, and a curiosity to learn about the interaction of software and hardware. The code is heavily inspired by the tutorials of One Lone Coder (javidx9) and his source code and hence will be using the same license.
Besides this, the nesdev.org website and PendleCodeMonkey's 6502 Emulator has also been very helpful.
This is in no way a working emulator and should not be used to play the games, it is just an attempt to learn how the NES works.
Disclaimer
This is a hobby project created for educational purposes to better understand emulation, computer architecture, and low-level programming. It is not complete yet. However, it is in a playable state and can be used to play a few games without any audio.
It has passed the basic list of the "nestest" tests and some of the illegal opcodes tests
And it runs Super Mario Bros
