While it's fortunate that all the LucasArts SCUMM games are available to purchase legally on digital storefronts like Steam and GOG.com, the situation is a bit of a mess in terms of the content of those purchases. There are a couple of conditions at play, none of which are particularly well advertised:
- In the case of games that had multiple release versions with content differences (commonly, EGA vs. VGA), usually only the latest is offered. In the case where an additional version is thrown in, it isn't documented.
- Depending on when and where the game became digitally available, it either uses a Windows friendly interpreter updated by Aaron Giles, or it comes bundled with ScummVM in place of the interpreter. In come cases, the original interpreter is also thrown in. Again, this is left for you to discover after buying it.
- The games that received special editions or remasters are only available that way, albeit with a togglable “classic mode” as a built-in feature.
For most people, ScummVM is a more than sufficient way of playing the games on modern machines, and thus, being able to buy the data files covers their needs. For those who insist on playing the games as faithfully as possible, an emulator is the way to go. Generally this means DOSBox, but Aaron Giles has teased an upcoming, SCUMM-specific emulator of his own design called DREAMM.
To exercise that option, you’ll need the original executables. Since there’s no rhyme or reason to which digital releases actually include those, and due to the other aforementioned inconsistencies, I thought a breakdown of what you actually get on Steam and GOG would be of some use to people. Here's what I knocked together:
