Credits

  • PistonMiner for creating the TTYD restarting loader stub, which has been ported to this project.
  • Zephiles for porting the TTYD restarting loader stub to Twilight Princess.
  • magcius (aka Jasper) for creating the TTYD save file hacker, which most of this repo's code is based off of. (GitHub repo for this can be found here)

Overview

This is a simple webpage for hacking a The Legend of Zelda: Twilight Princess GCI save file to load a REL file from memory card slot A.

Usage

The webpage part of this project is on Github Pages, which can be found here. You simply upload a proper gci file, select the file in it to hack, and then click the hack button.

Prerequisites

Node.js (can be found here)
Yarn (can be found here)

ts-node also needs to be installed with Node.js. The details for doing so can be found here.

Building

Once the prerequisites are installed, navigate to the root of the SaveFileHacker directory in a command prompt, and run yarn install. If you start getting errors such as Binaries/generate_data.ts:4:23 - error TS2307: Cannot find module 'path', then running yarn install --check-files from the root should resolve them.

The assembly codes that will be injected into the save file are stored at Binaries\bin. To use them, they must be converted to strings. To convert the bin files to strings, run ts-node Binaries\generate_data.ts from the root. This will remake BinaryData.ts, which contains the strings for the bin files. These should then be placed inside of WebVersion\main.ts.

Once the bin file strings are placed, main.js can be rebuilt by running tsc WebVersion\main.ts from the root. Once main.js is rebuilt, it can be placed in the gh-pages branch.
