NX2navi on Steam Deck and Linux

nx2 navi steam deck does not have a one-click Deck build. The published Setup is Windows. Linux support is a source-build note, and Deck play is unverified by the author.

If you want the supported path, use Windows. The launcher and Setup described in the docs install on Windows 10 or newer. Linux appears in the building notes as work in progress. The 0.6.0 notes say a native Linux build can be packaged as an AppImage. That sentence is not a Deck guide, and it is not a promise that Proton will launch the Windows Setup.

What issue threads actually cover

• Issue 36 reports build-tool downloads failing under Proton, including a name-lookup error while gathering tools.
• Issue 186 covers a shader prepare step failing under Wine while the game can still run and compile on demand.
• Issues 265 and 267 describe a black world with a visible HUD on Linux, and they record that NX2NAVI_SHADOW=1 did not restore the picture.
• Further Deck and Linux threads include 258, 267, 298, 109, 136, and 373. I am not collapsing them into one workaround.

Proton is a compatibility layer, not a platform the readme lists. Going back to a Windows PC is the only step the black-screen notes treat as solid. I will not invent a control layout, a Proton version, or a frame rate for NX2navi on Deck. The picture on this page from Gelibeans is labeled Hookshot on purpose.
