What does 'The selected disc image did not pass hash verification' mean?

Dusk computes an XXH128 hash of your ISO and compares against its internal whitelist of GameCube TP dumps. If the hash doesn't match, you see this error. The two accepted SHA-1 hashes are: 75edd3ddff41f125d1b4ce1a40378f1b565519e7 (NTSC-U) and 2601822a488eeb86fb89db16ca8f29c2c953e1ca (PAL). Anything else means corrupted dump, wrong region, scene release, or modified ISO.

How do I verify my dump's SHA-1?

Windows PowerShell: Get-FileHash -Algorithm SHA1 yourdump.iso. macOS / Linux Terminal: shasum -a 1 yourdump.iso. The output should match exactly one of the two accepted hashes.

What if my hash doesn't match either?

Re-dump from your own legally-owned disc using CleanRip, following the legal dump guide. Hash mismatches usually mean a corrupted dump (FAT32 split mishandled), a region the v1.0.0 release doesn't support yet (Japan, Wii, Wii Korea, Wii U HD), or a scene release (not a clean dump). If you want to use a modded ISO intentionally, Dusk shows a 'Continue anyway' option.

Dusk 'Disc Image Did Not Pass Hash Verification' — Fix

Dusk rejects your TP ISO with a hash-verification error. The two known-good SHA-1 hashes, how to verify your dump on every OS, and what to do if neither matches.

This is Dusklight telling you the ROM you pointed it at doesn’t match its internal whitelist of known-good Twilight Princess dumps.

The two accepted SHA-1 hashes (v1.0.x)

Region	Game ID	SHA-1
GameCube NTSC-U (USA)	`GZ2E01`	`75edd3ddff41f125d1b4ce1a40378f1b565519e7`
GameCube PAL (EU/AU)	`GZ2P01`	`2601822a488eeb86fb89db16ca8f29c2c953e1ca`

Source: src/dusk/iso_validate.cpp on the Dusklight repo. Player’s Choice and Best Of reissues share the same SHA-1 as the original.

Verify your dump

Windows (PowerShell)

Get-FileHash -Algorithm SHA1 .\twilight-princess.iso

macOS (Terminal)

shasum -a 1 ~/Games/twilight-princess.iso

Linux (Terminal)

sha1sum ~/Games/twilight-princess.iso

The output should match exactly (no spaces, no 0x) one of the two hashes above.

What “no match” usually means

Cause	What to do
Corrupted dump (FAT32 split file not reassembled)	Re-concatenate part0/part1 — see the legal dump guide
Wrong region (Japan / Wii / Wii Korea)	v1.0.x supports only NTSC-U + PAL. Other regions are planned per the project README
Wii U HD ISO	Wii U TP HD isn’t a GameCube disc image and Dusklight doesn’t play it. Use Cemu for HD
Scene release	”Scene” or NKit-converted dumps may differ. Re-dump from your own disc
Compressed format	Dusklight accepts ISO/GCM/CISO/GCZ/NFS/RVZ/WBFS/WIA/TGC, but each computes a different XXH128. If verification fails on a compressed dump, decompress to ISO first to rule out the converter

Loading a modded ISO intentionally

If you’re using the Linkle character mod or another ISO patch, the hash will not match — that’s expected. Dusklight shows a warning but offers a “Continue anyway” option:

“Just install the mod as you usually would directly to the GameCube or Wii .iso and then direct Dusklight to that modded .iso file and confirm that you still want to use it when it tells you it’s probably corrupted or modified.” — TomoAries, r/pcgaming (14 upvotes)
