Nintendo 3DS has hidden mode for DS 1-1 pixel playback
Stretched Nintendo DS graphics got you down? Dont worry you can turn it off
The Nintendo 3DS is completely backwards compatible with Nintendo DS titles, we all know that. What weve always known too is that the Nintendo 3DS would upscale and slightly blur Nintendo DS titles on the screen, theres a bunch more pixels on both the top and bottom 3DS screens.
1:1 Pixels
However, news of that hasnt pleased everyone, but dont worry you dont have to play your DS games like that if you want. Users of NeoGAF have discovered an undocumented mode in which you can boot to DS games and have perfect 1-1 pixel mapping. That means, no stretching, no blurring and you DS games look great on the new higher density screens – if a little bit smaller.
Stretched
All you have to do when booting into Nintendo DS mode is hold Start and Select. Thats it and youll be enjoying 1:1 pixels. The Start and Select button combo has previously been used on the Gameboy Advance to hold off booting from a cartridge in order to play single-cart multiplayer games. Tiny trivia there for you.
