Change Magic DOSBox’s  look with various opengl shaders.

 

The Filter option is a replacement for the older “Smooth” option. Version 1.0.25 introduces various “retro” shaders which can change  your game’s look and feel.

These shaders were originally used on the desktop PC and were converted for use on mobile devices. Unfortunately,  mobile devices have limited specs compared to PCs,  so only a small group of shaders are currently supported.

Supported shaders/filters :

• normal
• linear
• hq2x
• 2xSaI
• 5xBR lw
• 5xBR hq
• mcgreen
• mcamber
• grayscale

There are additional shaders like hq2x and hq4x which do heavy float calculations. Several mobile GPUs are ‘optimalized’ and these shaders will not work with these GPUs. But there are plenty of devices which work fine with them. Hq2x and hq4x filters will likely be included in version 26 with this caveat
