Game data & first launch
Use this after Install. Dusk targets The Legend of Zelda: Twilight Princess on Nintendo GameCube: you supply a legal disc image whose SHA-1 matches a supported retail build below. We do not host dumps or link to ROM sites.
GameCube disc images (.iso, .gcm) and this project
Guides and search phrases often mention a "Twilight Princess GameCube ISO." For Dusk, that really means "a supported retail GameCube rip of Twilight Princess." Common container extensions include .iso, .gcm, or files produced by ripping tools — the decisive check is matching one of the official hashes below, not the filename suffix.
If your hash differs, assume the rip is unsupported (wrong revision, patching, truncation, bad dump) until release notes cover it. Problems after a match? Try the FAQ.
1 · Verify your dump
Compare the SHA-1 of your image to a supported build below. If it does not match, Dusk may refuse the file or behave incorrectly. Other retail builds may be added over time — watch release notes.
| Version | SHA-1 |
|---|---|
| GameCube USA | 75edd3ddff41f125d1b4ce1a40378f1b565519e7 |
| GameCube EUR | 2601822a488eeb86fb89db16ca8f29c2c953e1ca |
Goal: a clean, byte-identical image of a disc you own. Examples with built-in tools:
- Windows (PowerShell):
Get-FileHash -Algorithm SHA1 .\path\to\dump.iso - macOS:
shasum -a 1 /path/to/dump.iso - Linux:
sha1sum /path/to/dump.iso
2 · Launch Dusk
Open the app from your install location (Install). You should land in Dusk's launcher: pick a disc image, optionally adjust settings the build exposes, and start once the file is accepted.
3 · Select disc image
- Choose Select Disc Image (or the equivalent entry in the menu).
- Point Dusk at your verified GameCube dump file on disk or on-device storage (Android/iOS paths differ).
- Press Play once the image is accepted.
On mobile, file pickers and storage permissions vary — use Android and iOS install notes alongside this flow.
Common questions
- Does this site provide Twilight Princess files or ISO links?
- No — only how to install Dusk and how to verify your own GameCube rip.
- Can I use any Zelda Twilight Princess GameCube dump?
- Only if its SHA-1 matches a supported retail entry in the table. Other regions or edited images are not covered here unless noted in upstream release docs.
- ISO vs GCM — which do I need?
- Extensions are shorthand; correctness is checksum + clean rip. Re-verify after any conversion or patching.
- Is Wii supported?
- These steps target supported GameCube builds. Wii or other SKU support is announced with the engine — check twilitrealm.dev and the FAQ.
- Where do I report bugs?
- Use GitHub Issues for the engine; use contact only for this website.
