=== Improve SCI support ===
Technical contacts: Our SCI team; talk to us on IRC, or send an e-mail.
Difficulty level: Hard. Good C++ knowledge and some knowledge of x86 assembly.
ScummVM has stable support for the older Sierra SCI games, but the newer ones -- such as Space Quest 6, Quest for Glory 4, Gabriel Knight 1 -- still need extensive work. As this is also something we are very actively working on ourselves, please come talk to us if you would be interested in helping out with reverse engineering and re-implementation.


=== Mission Supernova games ===

We got hold of the original source code written in C with some x86 assembler. We need to rewrite these in a portable C++ and add support both Missions in one engine. If possible, a translation of the game texts into English, or developing tools for performing such translation could be a great advantage.

=== SLUDGE engine ===
Technical contacts: [[User:Sev|Sev]]
Difficulty level: Medium/Hard
[https://opensludge.github.io/ SLUDGE] is an engine and adventure game development environment, developed by Hungry Software, and open sourced in 2008. It has number of games created with it. The goal of this project is to port the Engine to ScummVM, so games, made with SLUDGE, could be run.


=== Bring your own Adventure or RPG ===

Our current Android port is in need of improvement, especially combined with modern versions of Android. We'd like to improve the GUI and the input code in particular, but hopefully you also have your own ideas if you've tried the port (if you haven't: do so!). There are some patches already available, and it should be possible to merge code from other projects (such as SDL 2). A native configuration GUI could also be an option.

=== Improve audio device configuration ===
=== Native OS X port ===
Technical contacts: [[User:somaen|Einar Johan Trøan Sømåen]], [[User:aquadran|Paweł Kołodziejski]].


Technical contact: [[User:LordHoto|Johannes Schickel]].
Difficulty level: Medium. You'll need to know C++ and Objective C (and ideally have some Cocoa experience), and have a Mac.


Difficulty level: Medium. You'll need enough C++ experience and knowledge to design a suitable solution.
ScummVM's current OS X port is based on SDL 1.2, which is a dead project (having been replaced by SDL2); this means that the current state of the OS X port seems to degrade with each new OS X release. Also, functionality added in newer releases of OS X (such as the new full-screen modes introduced in 10.7) are not available for use in ScummVM.
 
One option for solving this would be to create a backend for OS X that doesn't use SDL. This would mean writing/porting replacement code for the parts where SDL currently handles things (i.e. at least audio, video and input, and ideally other details too). Preferably, such a project would be to retain backwards compatibility with 10.2 as we have today, while also allowing for a good user experience on the very latest OS X versions.


Our configuration currently doesn't support all the audio and MIDI options we would like, and even common configurations cannot always be conveniently specified.
=== Game packaging system ===


See [[OpenTasks/Audio/Audio Output Selection]] and [[OpenTasks/Audio/MIDI Device Configuration]] for more discussion and some technical details of two possible tasks in this direction.

=== Hardware accelerated blitting ===
ScummVM offers 8 freeware games for download, but they need to be downloaded and installed manually. It would be great to develop a universal system which would let us descibe a game, e.g. provide screenshots, game descriptions, metadata, and package it for different platforms, so we could put them to different applicaiton distribution systems.
Technical contacts: preferably [[User:LordHoto|Johannes Schickel]], otherwise [[User:somaen|Einar Johan Trøan Sømåen]], [[User:Fuzzie|Alyssa Milburn]] or [[User:Digitall|David G. Turner]]


Difficulty level: Medium. Some knowledge of graphics APIs (ideally OpenGL) would help, and ideally a mobile device of some kind which can run ScummVM, to experiment with.
Examples are: Linux packages, Google Play, Apple App Store, Steam, ForgeTV store, and anything beyond that.


Some engines (such as Wintermute and Broken Sword 2.5) would greatly benefit from hardware acceleration for their graphics code. Since this is not possible for all ports, an important part of this work would be developing a suitable API.
=== Support for shaders and arbitrary scalers ===


See [[OpenTasks/Graphics/Hardware Acceleration]] for more details.

=== Native OS X port ===
Difficulty: Medium
Technical contacts: [[User:somaen|Einar Johan Trøan Sømåen]], [[User:aquadran|Paweł Kołodziejski]].
 
ScummVM uses software scalers for graphics enhancements. In 2012 we were running GSoC for turning them into plugins. [https://github.com/scummvm/scummvm/pull/271 That work] needs to be completed, basically, it is just rebasing of the patch. The rebasing was started here: https://github.com/digitall/scummvm/tree/gsoc2012-scalers-cont


Difficulty level: Medium. You'll need to know C++ and Objective C (and ideally have some Cocoa experience), and have a Mac.
Modern systems often have OpenGL with shader support. RetroArch project shaders are standard for them in open source gaming. LordHoto started work on adding support for those to ScummVM. His unfinished work could be found here: https://github.com/lordhoto/scummvm/tree/libretro-shader


ScummVM's current OS X port is based on SDL 1.2, which is a dead project (having been replaced by SDL2); this means that the current state of the OS X port seems to degrade with each new OS X release. Also, functionality added in newer releases of OS X (such as the new full-screen modes introduced in 10.7) are not available for use in ScummVM.
We need to add both improvements to our scaler system. Recent PSP2 port already adds some basics for scalers, particularly in GUI, so that could be reused too.

This would mean writing/porting replacement code for the parts where SDL currently handles things (i.e. at least audio, video and input, and ideally other details too). Preferably, such a project would be to retain backwards compatibility with 10.2 as we have today, while also allowing for a good user experience on the very latest OS X versions.
We need to have it tested on desktops and at least Android, but preferably also Windows and iOS.
