Assuming the NES view of Hyrule is plate carrée, how might it look under other projections? Fortunately, I just saw a talk by Rob Simmon (which has corresponding detailed articles) about how to use these gdalwarp (one of a set of powerful geospatial tools provided by GDAL) to find out!
Doo doo doo! This is Link finding things on the web and holding them up for you to see, as he does! Except he's doing it on Twitter instead of your NES, which doesn't even work unless you hold in the cartridge a certain way.
