By the time these games enter the public domain, there'll be no way to play them except via an emulator and no way to develop an emulator if there's not one already - the flash holding the OS on all the Wiis out there will have long bitrotted away. Hell, a lot of the newer Wii Us are already dying due to flash failure just from being switched off for a few years. Strict copyright and DRM enforcement would most likely lead to this era of games being lost forever, just like many older films from a century or more ago have been lost.
