    I was wondering just how it works. How does it add extra image on the sides when its never intended to?

    3d games still have the whole world in memory but choose only to render a slice of it (see viewport rendering for one of the names of techniques here).
    You increase the size of this slice (possibly also correct for any overlays and 2d elements put on top of it as a UI or something, this may need to be done on a game by game basis) and you are good.

    This is far harder in 2d games which do tend to assemble things on the fly (why most things like this are emulator only, and do things like make a savestate, move in all 4 directions, assemble results from results, restore original savestate, hope no random battles or NPC behaviour happened in the meantime) but if 3d is just a matter of expanding the camera viewing angle a bit to capture data already there then it is easy enough. Some 3d systems can be more tricky than others, and it can be harder within the same system (though far from impossible -- plenty of games had high res or widescreen modes on such things in different regions) where the Wii technically has all the Wii's resources in addition to being basically a gamecube and thus dodging most of the resource requirement penalties of emulation.
