Building a Gameboy Emulator with Rust - EP 12

his is the episode 12 of a series of Twitch streaming sessions where I will be building a Game Boy emulator from scratch using Rust Programming Language. - Made some fixes pointed by SaturnoZmarte in previous Youtube videos. - Started with minifb - Created some debug functions to be able to see the tileset data.

Serde Rust: Serialization Framework for Rust

Serde

*Serde is a framework for serializing and deserializing Rust data structures efficiently and generically.*

You may be looking for:

Serde in action

Click to show Cargo.toml. Run this code in the playground.

[dependencies]

# The core APIs, including the Serialize and Deserialize traits. Always
# required when using Serde. The "derive" feature is only required when
# using #[derive(Serialize, Deserialize)] to make Serde work with structs
# and enums defined in your crate.
serde = { version = "1.0", features = ["derive"] }

# Each data format lives in its own crate; the sample code below uses JSON
# but you may be using a different one.
serde_json = "1.0"

 

use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize, Debug)]
struct Point {
    x: i32,
    y: i32,
}

fn main() {
    let point = Point { x: 1, y: 2 };

    // Convert the Point to a JSON string.
    let serialized = serde_json::to_string(&point).unwrap();

    // Prints serialized = {"x":1,"y":2}
    println!("serialized = {}", serialized);

    // Convert the JSON string back to a Point.
    let deserialized: Point = serde_json::from_str(&serialized).unwrap();

    // Prints deserialized = Point { x: 1, y: 2 }
    println!("deserialized = {:?}", deserialized);
}

Getting help

Serde is one of the most widely used Rust libraries so any place that Rustaceans congregate will be able to help you out. For chat, consider trying the #rust-questions or #rust-beginners channels of the unofficial community Discord (invite: https://discord.gg/rust-lang-community), the #rust-usage or #beginners channels of the official Rust Project Discord (invite: https://discord.gg/rust-lang), or the #general stream in Zulip. For asynchronous, consider the [rust] tag on StackOverflow, the /r/rust subreddit which has a pinned weekly easy questions post, or the Rust Discourse forum. It's acceptable to file a support issue in this repo but they tend not to get as many eyes as any of the above and may get closed without a response after some time.

$ cargo run --release -- "./res/boxes.gb"

The following options are supported:

-a, --enable-audio    Enable audio, default is false
-x, --scale-factor    Scale the video by a factor of 1, 2, 4, or 8

Gameboy is developed by Rust, and fully tested on Windows, Ubuntu and Mac.

Tests

Thanks for Blargg's Gameboy hardware test ROMs, I can simply verify my code. Run tests by:

$ cargo run --example blargg

Building a Gameboy Emulator with Rust Programming - EP 16

This is the episode 16 of a series of Twitch streaming sessions where I will be building a Game Boy emulator from scratch using Rust Programming Language.

  • I fixed the viewport problem
  • Load a real Tetris ROM and implemented the check for reading the Boot Rom first.
  • FINALLY, WE WERE ABLE TO SEE THE NINTENDO LOGO! :)
  • But we get some slowness problem! :( Which I will work to solve tomorrow, stay tune!
