when people play emulators they stretch the heck out of the image.
That's generally a completely different scenario. Emulators actually render the games at a higher resolution, essentially giving them a higher native resolution, whereas backward compatible consoles just upscale the original low resolution output to fit the screen. Obviously the former looks far better than the latter.
no, i was talking about when people use visual boy advance etc in native resolution and just multiply the screen by 2x etc . no , it is not rendered in a higher resolution.
On an XL and with the ds game in native mode, (native mode is when you start the game while holding down the start or select button on the XL, while starting a ds game. This shrinks the Ds' games size.), the Ds game will be pixel for pixel the same as it is on a real DS lite and look as good as it did on a ds lite. On an XL, with the ds game in native mode, that ds game will be very close to being the same size as on a DS Lite. It's only when you don't start a ds game in native mode that you get the odd stretching that makes the picture look a little fuzzy. This doesn't seem to be too bad on the XL. If you do native mode on a ds game on an xl that picture for the ds game will still end up bigger then non native mode for that same ds game on a regular 3ds.
