Why does Dusk say 'The selected game is not supported'?

Dusk v1.0.x supports only the GameCube NTSC-U (GZ2E01) and PAL (GZ2P01) releases of Twilight Princess. Any other region or platform — GameCube Japan, all Wii versions (NTSC-U / NTSC-J / PAL / Korea), Wii U HD — is recognized but rejected at load. NTSC-J and Wii region support is on the project's stated roadmap; Wii U HD is not.

When will Wii support land?

No firm date. TwilitRealm has stated Wii NTSC-U, NTSC-J, PAL, and Korea are planned. The gating dependency is upstream zeldaret/tp Wii decompilation, which sits around 53% as of May 2026.

What about the Wii U HD remaster?

Dusk will not play TP HD. HD is a separate Tantalus Media + Nintendo EPD codebase, not a GameCube disc — different game data, different engine tweaks. To play HD on PC today, use Cemu. See our Dusk vs Cemu comparison for which version is right for you.

Dusk 'The Selected Game Is Not Supported' — Region & Version Guide

Dusk v1.0.x only accepts GameCube NTSC-U and PAL Twilight Princess. Why your Japan / Wii / Wii U HD dump fails, and what to do per region.

Published 2026-05-14 ·Updated 2026-05-14

Dusklight v1.0.x recognizes a handful of Twilight Princess Game IDs but only two are actually supported. Everything else gets this error.

What v1.0.x supports

Game ID	Region	Status
`GZ2E01`	GameCube NTSC-U (USA)	✅ Supported
`GZ2P01`	GameCube PAL (Europe / Australia)	✅ Supported
`GZ2J01`	GameCube Japan (NTSC-J)	⏳ Recognized, planned
`RZDE01_00`, `RZDE01_02`	Wii NTSC-U	⏳ Recognized, planned
`RZDP01`	Wii PAL	⏳ Recognized, planned
`RZDJ01`	Wii NTSC-J	⏳ Recognized, planned
`DZDE01`	Wii Korea	⏳ Recognized, planned
Wii Shield / Demo	Special builds	⏳ Tracking

If your dump’s Game ID is in the “Recognized, planned” rows, Dusklight identifies it but won’t run it yet. The error message is honest: “not supported” means support hasn’t shipped, not that the dump is broken.

What to do per region

You have a GameCube Japan disc

Wait. NTSC-J is on the roadmap. Track github.com/TwilitRealm/dusklight releases or use Dolphin for GC Japan in the meantime.

You have a Wii disc (any region)

Same answer: wait for Wii support, which depends on the upstream zeldaret/tp Wii decomp (~53% as of May 2026). For now, Dolphin plays Wii TP at 30 FPS reliably; see Dusklight vs Dolphin.

You have a Wii U HD copy

Dusklight will never play HD — different codebase. To play HD on PC today, use Cemu. See Dusklight vs Cemu for which version fits your situation.

Your disc is GameCube NTSC-U or PAL but you still hit this error

That’s a different problem — most likely a hash mismatch even though the Game ID is right. See Disc Image Did Not Pass Hash Verification.
