+ may require less CPU power than other solutions, like DOSBox + screenshot function (not perfect, but very usable) There are some things that ScummVM doesn't faithfully replicate, like say the hi-res dithered EGA graphics driver for Sierra SCI1.1 games. With ScummVM it's basically plug & play, start and go. To be fair, DOSBox is also ported to multiple systems but unless you're versed in DOS configuration it can be a pain to get up and running, plus there's probably more memory usage overhead in using DOSBox than ScummVM. ScummVM's benefits (besides what I mentioned earlier) is the ability to play supported games on any system ScummVM is ported to (with some exceptions for certain games sometimes). Most differences would be under the hood and not obvious to the average player. Though, for the most part the playing experiences are pretty much exactly the same because everyone involved has simply done some darn good work. Sometimes this comes with some benefits (like playing KQ6 with the high res dialogue portraits from the Win3.x version but with the coloured cursors of the DOS version) but it's a result of reverse engineering the game code and interpreting what it was supposed to do as best as can be told from experimentation, so the replication is not 100% the same even though it's the same game files. ScummVM replaces the game executable so that the game can run on modern operating systems instead of DOS. So for me the main advantages using ScummVM for games supported by it compared to DOSBox are: easier to set up, can play on more platforms including Android/iOS mobile devices, no game speed issuesĭOSBox provides a compatible environment to run the original game executable authentically exactly as it did in DOS back in the day (more or less). There are probably a lot of more advantages and porrible also a few disadvantages. with ScummVM you don't need to care about emulation speed, while in DOSBox you often have to modify the cycles so that the game is running with speed feeling natural or to play with sound that doesn't stutter or having issues once you have a folder needed for ScummVM you can copy them to all devices you own and can run ScummVM (e.g. with ScummVM you often don't need to install & setup the games using the old DOS installation/setup programs, you just have to copy the resource files ScummVM needs If you take the different concepts into account you can imagine a couple of advantages: That is the reason why only certain games are supported (games using the engines that have been rewritten for ScummVM) and why ScummVM has ports to a lot of different operating systems & platforms. Instead a couple of engines have been rewritten in a way that they can run in different environments (operating system & platform wise). ScummVM on the other side doesn't do that. It's a kind of hard to compare them because they have a very different concept.ĭOSBox emulates a complete operating system (DOS) and hardware typical for former systems running DOS.
