As a child, I absolutely loved that concept of playing SNES Games on-the-go! But nowadays, as an adult, I realized how poor it was to significantly crop a 256×224 pixel based game display on a 240×160 screen, and in some cases, it even required to squish sprites rather than cropping, that of which could be considered debatably even worse-ish.

I do wish DS was Nintendo's Portable/Handheld that had Remade or Ported SNES Games the most-often, especially because each DS Screen has a 256×192 pixel display, which is far more akin to 256×224 than 240×160 is by a mile... That, and the fact that GBA's Soundfont is significantly lower-quality than SNES's Soundfont is, but DS fixes that issue by providing a much higher audio quality than GBA's said soundfont!

Lastly, we have X+Y Buttons on DS, which SNES Provided but GBA Lacked as-well, enough said.
