base on NES emulator in rust with egui and TUI <p align="center"> <!-- Really ugly workaround, but the image isn't working in crates.io without this --> <a href="https://github.com/Amjad50/plastic"><img alt="plastic" src="https://raw.githubusercontent.com/Amjad50/plastic/refs/heads/master/images/logo.svg" width="60%"></a> <p align="center">NES emulator in <em>Rust</em></p> </p> [](https://actions-badge.atrox.dev/Amjad50/plastic/goto) [](https://codecov.io/gh/Amjad50/plastic) [](https://deps.rs/repo/github/Amjad50/plastic) [](./LICENSE) <br> [](https://crates.io/crates/plastic_core) [](https://docs.rs/plastic_core/latest/plastic_core/) <br> [](https://crates.io/crates/plastic) [](https://crates.io/crates/plastic_tui) **plastic** is a [NES][NES-wiki] emulator built from scratch using [Rust][Rust]. This is a personal project for fun and to experience emulating hardware and connecting them together. - [Building and installation](#building-and-installation) - [Dependencies](#dependencies) - [Installing](#installing) - [Building](#building) - [Components](#components) - [Interfaces](#interfaces) - [EGui UI](#ui) - [TUI](#tui) - [Controls](#controls) - [Keyboard](#keyboard) - [Gamepad](#gamepad) - [License](#license) - [References](#references) ### Building and installation #### Dependencies For linux, this project depends on `alsa` and `libudev`, you can install them using: ```sh # Debian/Ubuntu sudo apt install libasound2-dev libudev-dev # Arch sudo pacman -S alsa-lib systemd-libs ``` #### Installing You can install the latest version of [plastic](https://crates.io/crates/plastic) or [plastic_tui](https://crates.io/crates/plastic_tui) using cargo: ```sh cargo install plastic cargo install plastic_tui ``` If you are using Debian/Ubuntu, you can directly install the `.deb` package from [here](https://nightly.link/Amjad50/plastic/workflows/rust/master/plastic.deb.zip) ```sh unzip plastic.deb.zip sudo dpkg -i plastic_*.deb # will have the version in the name ``` If you are using Arch Linux, `plastic` is available in the [official repositories](https://archlinux.org/packages/extra/x86_64/plastic/): ```sh pacman -S plastic pacman -S plastic_tui ``` #### Building If you want to experience the latest development version, you can build `Plastic` yourself. For example: ``` cargo run --release ``` ### Components - [x] 6502 CPU, all official and unofficial instructions with accurate timing (without BCD mode). - [x] Picture Processing Unit, almost accurate with some small timing issues that would not effect most games. - [x] Cartridge and INES file handling (still missing INES2.0) - [x] Mappers: - [x] Mapper 0 - [x] Mapper 1 - [x] Mapper 2 - [x] Mapper 3 - [x] Mapper 4 - [ ] Mapper 5 (Milestone) - [ ] Mapper 6 - [x] Mapper 7 - [ ] Mapper 8 - [x] Mapper 9 - [x] Mapper 10 - [x] Mapper 11 - [x] Mapper 66 - [x] Audio Processing Unit: - [x] 2 Pulse wave(square) - [x] Triangle - [x] Noise - [x] DMC - [x] IRQ support - [x] Controller: controllable using the keyboard and controller (tested with PS4 controller) ### Interfaces The main emulator is at [`plastic_core`](./plastic_core/) And its a struct `NES`, where the UI would clock it, and then take the resulting audio and pixel buffers to handle them. We have 2 UIs, one main and the other just for fun. #### EGui UI Simple ui built with [egui] <!-- omit in toc --> ##### Advantages 1. Very simple and easy to use immediate mode UI. #### TUI [](https://www.youtube.com/watch?v=3wKILnY0AHU) This is just for fun, but it is actually working way better than I expected. Check the [full demo](https://www.youtube.com/watch?v=3wKILnY0AHU). If you have one of these terminals mentioned [in this docs](https://docs.rs/crossterm/0.28.1/crossterm/event/struct.PushKeyboardEnhancementFlags.html) Then you will have a much better experience, since these terminals support detecting button `Release`, normally other terminals don't have this feature, so the input for this UI can be a bit wonky. I used [gilrs][gilrs] for gamepad support and its working very nicely, keyboard on the other hand is not very responsive, so it is advised to use gamepad. Also since this uses one character for each pixel, it is advised to use the smallest font size your terminal emulator supports. Have fun. The gamepad support is for both UIs. ### Controls In all the UI providers I followed the same controlling scheme, as well as the ability to reset through `<CTRL-R>`: #### Keyboard | keyboard | nes controller | | -------- | -------------- | | J | B | | K | A | | U | Select | | I | Start | | W | Up | | S | Down | | A | Left | | D | Right | #### Gamepad | gamepad (PS4) | nes controller | | -------- | -------------- | | X | B | | O | A | | Select | Select | | Start | Start | | Button Up | Up | | Button Down | Down | | Button Left | Left | | Button Right | Right | For now its static, and there is no way to change it except for doing it in the code, TODO later. ### License This project is under [MIT](./LICENSE) license.
