Microsoft has released static links for Windows 11 25H2 Consumer x64/A64 (build 26200.6584).

Although version 25H2 has not yet been officially released to the public, these links suggest that build 26200.6584 is likely the RTM build.

A couple years ago I went to Japan and bought a Wii, two wiimotes with plus, two nunchucks, smash x, both mario galaxies, wii sports, and mario kart wii for about $18.
