"Because it's written in assembly, it's a pretty tough one. But there are exceptions, like Mission Supernova. Often the ScummVM team avoids using much original code. and I can say it's awful because they told us they were 14 or 15 or so and learning programming while doing it!" Sandulenko says. It's awful, but we got source and support. "If we have source code and right, we'll try and implement it, even if it's something like this freeware 'Drascula' game. One of the developers being particularly passionate about it.The two most common ways a game or engine gets into ScummVM are: ![]() We originally announced it as an April Fool’s joke, but… why not? Go play it!" There’s versions of Hello World longer than that! So it was pretty easy. Full Pipe, that’s about 31,000 lines of code. Well, in short, because we had a crazy developer willing to invest the time, maybe because of the. However, there is method to the madness-even the madness of devoting time to resurrecting Plumbers Don’t Wear Ties. It’s hard to imagine taking on this amount of work in the name of a completely forgotten Russian adventure game notable for little but being an early-ish Steam release. So, that's a year and a half on one game." It took ten months to implement it and start bug fixing, but it was only in 2016 I was able to pick it up again and finish it this year. Sandulenko demonstrates with a look at his last implementation, an obscure adventure called Full Pipe. Sometimes all this takes years, not months. Those different game versions each require more work. There's a lot of trial-and-error, and it's not a one time process. That mapping can take months, and then the ScummVM team has to convert the code into C or another language. We call the process of figuring it out 'mapping.'" all you're left with is taking an address from memory location X and use it as a pointer to another byte, and so on. Along the way you lose all the function names, all the variable names. "We take the original binary, and if you know the process of compilation, you'll know that turns high level programming code into assembly and then binary code. You want to run the Macintosh version of Indiana Jones, which was in black and white? We can do that in ScummVM. We have games based on SCUMM engines for Atari and Macintosh and Apple 2c and Amiga. Secondly of course, not all games were written for DOS or Windows. Something like DOSBox, you'd need about a gigahertz to run it. ![]() Something like Monkey Island was written in the CPC era, on slow machines, and our requirements for it are about the same. This is the major difference between emulators, like DOSBox and reimplementation, like ScummVM. "ScummVM started in 2001 and some of the platforms we were running on were only 25. "Well, the key words are ‘these days’!" Sandulenko points out. It does however mean development can look quite slow on the outside, especially since these days you can drop more or less anything into DOSBox and have it at least run acceptably. Some of the supported games include Day of the Tentacle, Gabriel Knight I and II, the Monkey Island Series, Broken Sword I and II, as well as the Indiana Jones series.This hand-crafted approach has given ScummVM a well-deserved reputation for quality. While the project concentrated on Lucas Arts adventure games in the beginning, hence the name ScummVM, it is now supporting a variety of classic games, including some of my all time favorite games.Ī list of all games currently supported is available here. ScummVM is an Open Source project that has been designed as an interface to make those old games playable again on modern PCs. Some came on CD on the other hand, but even those may not be playable right away due to changes in computer hardware and operating system. I have several of the old games still at home but cannot really play many of them considering that I do not have direct access to a floppy drive anymore. Lucas Arts made that genre popular, today it is just a shadow of its former past. ![]() You know, the click and point type of adventure games where you had to pick an action and combine that action with something or someone on the screen. Ever since the release of Maniac Mansion on the Commodore C-64, and probably even earlier than that (Guild of Thieves for instance), I was fascinated by adventure games.
