ScummVM contains by now over a dozen different engines for different adventure game systems. Each of these engines forms a "plugin", and it is possible to compile these plugins as loadable modules separate from the core of ScummVM itself. This makes it possible to (un)load engine code at will, ideal for systems with tight memory constraints; if you want to play a game, you only need to load the engine for that specific game, and can unload the others. | ScummVM contains by now over a dozen different engines for different adventure game systems.

ScummVM implements its own GUI code. We can't use any of the portable GUI kits out there, as they are mostly not portable enough, use too many resources, or simply are not flexible enough to work atop our backend system. Also, our GUI must look equally good with 8bit, 16bit or 32bit graphics, at 320x200, 320x240 or 640x480 resolutions -- and ideally also at 240x200 or at 1280x1024. | ScummVM implements its own GUI code.

Residual currently offers two different renderers: OpenGL and TinyGL. Neither offers an ideal solution. Not all OpenGL drivers accelerate the operations needed by Grim Fandango, and the TinyGL renderer, apart from being somewhat glitchy, doesn't run well on low-end hardware. It would be nice to have a more light-weight cross-platform renderer. Since Grim Fandango uses mostly static backgrounds, we could probably gain a lot just from more intelligent screen redrawing. | Residual currently offers two different renderers: OpenGL and TinyGL.

SCUMM engine starting v5 originally was developed for 8bit graphics. At version 6 it got forked by Humongous Entertainment which extended it significantly. Later games even started to use 16bits graphics for backgrounds graphics and actors. See [[Humongous Entertainment/Progress/16bits Support|here]] for more detailed information. | SCUMM engine starting v5 originally was developed for 8bit graphics.

Many games supported by ScummVM contain sound data intended for the [http://en.wikipedia.org/wiki/AdLib AdLib] Music Synthesizer Card, or other AdLib-compatible hardware like the SoundBlaster. These sound cards used the Yamaha YM3812 sound chip (also known as OPL2) to produce sound via FM synthesis. For more information about how this is done, see Jeffrey S. Lee's web page on [http://www.shipbrook.com/jeff/sb.html Programming the AdLib/Sound Blaster FM Music Chips]. | Many games supported by ScummVM contain sound data intended for the [http://en.wikipedia.org/wiki/AdLib AdLib] Music Synthesizer Card, or other AdLib-compatible hardware like the SoundBlaster.
