About

Wii Sports is a 2006 sports simulation game developed and published by Nintendo for the Wii, bundled with the console at launch in most territories and later re-released as part of the Nintendo Selects lineup. This is a work-in-progress decompilation of Wii Sports that currently supports only the US Revision 1 release (build date 2007/07/05, checkable via a button combination on the title screen). It contains no game assets or original assembly code — an existing legitimate copy of the game is required to build it.
