使用 rust 替换 v1.02 NTSC GALE01 中的 DAT 文件

简介

从 RC 发送：解析和转换超级炸弹人 melee

这是我曾在 The Recurse Center 做的演讲！

用法

此示例使用 dang3r 潜行灵感的 animelee 鹰

Cargo.toml:

[dependencies]
melee_inject = { git = "https://github.com/djanatyn/melee-inject" }

src/main.rs:

use melee_inject::characters::CaptainFalcon;
use melee_inject::replace::{build_iso, rebuild_fst, Replacement};
use std::io;
use std::path::PathBuf;

const SSBM_ISO: &str = "<path-to-ssbm.iso>";

fn main() -> io::Result<()> {
    let replacements = vec![
        // replace potemkin
        Replacement {
            target_file: CaptainFalcon::PlCaGr,
            replacement: PathBuf::from("<path-to-skin.dat>"),
        },
    ];

    let updates = rebuild_fst(SSBM_ISO, &replacements);
    std::fs::write("modified-fst.bin", &updates.new_fst)?;

    let rebuilt_iso = build_iso(SSBM_ISO, &updates);
    std::fs::write("modified-melee.iso", rebuilt_iso)?;

    Ok(())
}

之后，你应该能够在 dolphin 中加载重建的 ISO！
