Shaders are computer programs that can be used to modify the appearance of graphics. They can be used to add effects such as bloom, glow, and depth of field. MGBA and RetroArch are two emulators that support shaders. This guide will show you how to use shaders with these emulators.
Shaders can be used to improve the visual quality of retro games. They can also be used to create new and unique visual effects. For example, you can use a shader to make a game look like it’s being played on an old CRT TV. Or, you can use a shader to add bloom and glow effects to a game.
