One of the stranger success stories involves the animal-themed fantasy Inherit The Earth. Of course, we're volunteers, so we couldn't make any promises, but they patiently waited and then we helped them bundle it with ScummVM for distribution.' 'They told us they'd give us the source for reimplementation because they wanted to put it back in stores. In particular, Sandulenko recalls working on the game Tony Tough, whose IP owners wanted to return to shelves. ScummVM has also been instrumental in getting games back on sale, either with or without the help (or appropriate credit) of the team.

It got a big boost when Revolution Software re-released Beneath A Steel Sky as freeware, with Dreamweb, Lure of the Temptress, and Flight of the Amazon Queen joining a couple of smaller games as free to download demos.

The project hasnвЂ™t always had the easiest relationship with developers and publishers, though that has slowly changed over time. If the source is in C or whatever and the author is okay with us just stripping out their comments and stuff, that's much easier.' '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 FoolвЂ™s joke, butвЂ¦ why not? Go play it!' ThereвЂ™s versions of Hello World longer than that! So it was pretty easy.

Full Pipe, thatвЂ™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 DonвЂ™t Wear Ties. ItвЂ™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 вЂthese daysвЂ™!' 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. This hand-crafted approach has given ScummVM a well-deserved reputation for quality.
