These are just the few projects that we have come up with ourselves, and there are many many other tasks which would be helpful to the project - many ScummVM engines have their own TODO lists, and there are large tasks related to ResidualVM engines.

Many 90s-era adventure games were developed using the Macromedia (now Adobe) Director tool. They don't run any more on modern systems, and current versions of Director can't even open the files (and too much has changed; Macromedia themselves have said that "reauthoring the movie from scratch" is often more efficient). It would be nice to be able to play these games in ScummVM!

There is already (Python) code available which can parse and display the contents of Director 2 and Director 3 'movie' files, and the basic framework of a ScummVM C++ engine. The task would involve trying to implement enough of a SummVM engine to allow some early Director adventures to be played; for example, parsing the movie files, implementing the frame-based playback system, drawing bitmaps and shapes, playing sounds and running some basic (Lingo) scripting.

=== Port WebVenture engine ===
 +
Technical contacts: [[User:DJWillis|John Willis]], [[User:Md5|Filippos Karapetis]].
 +
 +
The [http://seancode.com/webventure/ WebVenture] [https://github.com/mrkite/webventure engine] by Sean Kasun is a reimplementation of the [https://en.wikipedia.org/wiki/MacVenture MacVenture] engine from ICOM Simulations.
 +
 +
It was used in the late 80s and in the early 90s for 4 games. The MacVenture games are still available for purchase from [http://www.zojoi.com/ Zojoi].
 +
 +
The current code is written in JavaScript, which means it will have to be completely rewritten in C++ and integrated in ScummVM.
 +
 +
'''This task requires C++ and JavaScript knowledge.'''
 +
 +
=== Native OS X port ===
 +
Technical contacts: [[User:somaen|Einar Johan Trøan Sømåen]], [[User:aquadran|Paweł Kołodziejski]].
 +
 +
ScummVM's current OS X port is SDL 1.2 based, which is a dead project, having been replaced by SDL2, and Apple has a tendency to change and deprecate functionality with each version of their OS, as such, the current state of the OS X port seems to degrade with each new OS X release. Functionality added in newer releases of OS X, such as the new Full-screen modes introduced in 10.7 are also not available for use in ScummVM with the current SDL1.2 port.
 +
 +
One option for solving this, is to create a backend for OS X that doesn't use SDL. This would mean writing replacement code for the parts where SDL currently handles things (i.e. atleast audio/video/input, but possible other details). A major aim of such a project would be to retain backwards compatibility with 10.2 as we have today, while allowing for a good user experience on the very latest OS X versions as well.
 +
 +
'''This task requires C++ and Objective-C/Cocoa knowledge.'''
 +
 +
=== Improving the iPhone/iOS port ===
 +
 +
Technical contact: [[User:LordHoto|Johannes Schickel]], [[User:Sev|Eugene Sandulenko]].
 +
 +
The current iOS port, which we still label as iPhone, is functional but feels not really polished in a number of ways. The port comes from a time when the first two generations of the iPhone were still the top models. This, for example, makes it not as nicely usable on modern iOS devices because of resolution issues. Furthermore, while the gesture input serves as a great way to, for example, change control schemes, it also has some annoying issues. The most prominent example is that the "open global main menu" gesture sometimes causes the main menu to immediately close.
 +
 +
Build wise the iOS port is currently only supported by using a custom toolchain. Supporting the official toolchain and XCode as development environment in '''addition''' to the current toolchain is something we would really like to see. We already have a tool to auto-generate project files for Microsoft Visual Studio. The idea would be to take the currently WIP XCode support and finish it. Building with the official toolchain on command line would also be nice to have.
 +
 +
Essentially, this task requires working on various aspects of the iOS port. This includes graphics, GUI, input handling, but also build related aspects. Ideally, we want our iOS port to feel much smoother for the users, but also for developers working on it.
 +
 +
'''This task requires C++, ObjC(++), and iOS development knowledge. It also requires access to a (jailbroken) iOS device, preferable both iPhone and iPad, and the official iOS development environment.'''

If you already have reverse engineering experience, you could consider working on one of the external in-development game engines, or even on support for a new game. However, doing this kind of work is very difficult and time-consuming - you would have to convince us that you have the necessary skills to actually be sufficiently productive, probably by demonstrating some actual progress first.
