MAME.
They are:
-gnormal - No filtering, original 320x200 resolution. Fastest.
-g2x - No filtering, double screen/window size to 640x400 (default)
-g3x - No filtering, triple screen/window size to 800x600
-g2xsai - 2xsai filtering, double screen/window size to 640x400
-gsuper2xsai - Enhanced 2xsai filtering. 640x400 screen/window size
-gsupereagle - Less blurry than 2xsai, but slower. Also 640x400
-gadvmame2x - 640x400 scaling. Doesn't rely on blurring like 2xSAI.

To select a graphics filter, pass its name via the '-g' option to scummvm, for example:
scummvm -g advmame2x monkey2
Note #1: Bot all backends support all or any filters. The ones listed above
are for the default SDL backend.
Note #2: Filters can be very slow when ScummVM is compiled in a debug
configuration without optimizations. And there is always a speed impact when
using any form of anti-aliasing/linear filtering. Also note that the FmTowns
Zak (zak256 target) uses an original resolution of 320x480 - hence for this
game scalers will be 640x480 and 960x720.
using any form of anti-aliasing/linear filtering.
Note #3: The FmTowns version of Zak (zak256 target) uses an original resolution
of 320x240 - hence for this game scalers will scale to 640x480 or 960x720.
The alternative to these scalers is to try using the SDL_gl.cpp target. This
will allow you to use hardware accelerated functions, like bilinear filtering
and FSAA, on suitable OpenGL capable cards.
