As well as digital game manuals, Game Boy Advance games on Wii U will also include options to smooth and tweak the resolution.
Due to the relatively small resolution of the original Game Boy Advance releases, Nintendo have had to consider the leap from portable to big screen when it comes to preserving the look and offering a smooth experience.
NintendoInsider reports that there'll be numerous display options for GBA games on the Wii U, with the option to trigger a real-time "smoothing" effect, but also the option to play in the game's original resolution - scaling up the game to 1440×960. The default option, though, is a 1620×1080 - 6.75x the original 240×160 output.
In terms of lighting and colour, the Wii U releases have had some alterations to remove the artifical brightness from the GBA originals, resulting in a fairly darker picture on the GamePad screen.
Would you like to see these display options for more Nintendo classic platforms like NES or SNES?
