A NES emulator 100% written in Rust

This project is my first big coding project and also my first big emulator project.

I chose Rust because it's fast and it's by far my favorite language. Also all the code is 100% safe Rust!

The emulator is not cycle accurate, but all the games I've tried work pretty well. Based on the mappers I implemented, appart from a few exceptions, ~90% of games should work.

The program needs libsdl2 to run and libsdl2-devel to compile. It works on Linux, Windows and MacOS

Launch: ./nesoxyde [SyncMode] <iNES File>

SyncMode:

• Audio sync (default): The emulation is synced with the audio sample rate (44100Hz). Can cause frame lag.
• Video sync (-V): The emulation is synced with the video refresh rate of 60fps. Can cause audio pops and cracks.

R -> Reset
Esc -> Close emulator
1 -> Volume down
2 -> Volume up
F1 -> Save state
F2 -> Load state

Joypad:

• A -> B
• S -> A
• Z -> Select
• X -> Start
• UpArrow -> Up
• DownArrow -> Down
• LeftArrow -> Left
• RightArrow -> Right

• Make the CPU and PPU cycle accurate
• Change the sprite rendering routine to match what real hardware does
• Fix some mapper bugs (4 doesn't work with every game)
