===Oversaturation===
[[File:1406913527173-1-.png|400px|thumb|right|'''Left:''' The default game.<br/>'''Right:''' The "Gameboy Colors" mode on [[VisualBoy Advance#VBA-M|VBA-M]].]]
The screen on the original Game Boy Advance is not backlit and can be hard to see in some conditions. To compensate, game developers often used oversaturated colors by default so that the result would look normal on hardware. On standard computer screens, saturation is not an issue , so this can look jarring and undesirable for gameplay. Some games made after 2003 may have also taken the Game Boy Advance SP <abbr title="AGS-001">model</abbr> into account , since its screen was actually <abbr title="A newer model, AGS-101, was released in 2005 that was actually backlit">frontlit</abbr>. For everything else though, emudevs have given some solutions:
====Emulator Options====
There is also <code>nds-color.cg</code><ref>https://github.com/libretro/common-shaders/blob/master/handheld/shaders/color/nds-color.cg</ref> and <code>psp-color.cg</code><ref>https://github.com/libretro/common-shaders/blob/master/handheld/shaders/color/psp-color.cg</ref>, which simulates the color profiles of the original Nintendo DS frontlit screen and the PSP-1000/PSP-2000 backlit screen, respectively.
For Game Boy Advance shader presets , see the "Shader Presets" page;

Similar to the scaling effects used on the Super NES known commonly as "Mode 7" graphics, the Game Boy Advance has affine transformation effects for some backgrounds and individual sprites that can be done in hardware. Due to the GBA's lower resolution, some detail may be lost.
The [[mGBA]] emulator added an Enhancements ' menu where you can change the resolution of those graphical effects, for a smoother effect. The graphical render engine will need to be OpenGL for those to take effect. It won't work on games where those effects are done in software instead of the hardware scaling features (like the 3D environment in Asterix & Obelix XXL)
