Let's pick some old classic game, reverse engineer the data formats and game rules and write an open source engine for it from scratch. Some games from 1990s are simple enough that we could have a playable prototype by the end of the week.
Write which games you'd like to hack on in the comments. Don't forget to check e.g. on Open Source Game Clones, Github and SourceForge whether the game is ported already.
Hack Week 24 - TBD
It's time to choose the game for the upcoming Hack Week. Discuss what you'd like to hack on in the comments.
Hack Week 20, 21, 22 & 23 - Master of Orion II: Battle at Antares
Master of Orion II is one of the greatest turn-based 4X games of the 1990s. Explore the galaxy, colonize planets, research new technologies, fight space monsters and alien empires and in the end, become the ruler of the galaxy one way or another.
How to install & play:
- Clone the Git repository
- Run
./bootstrap; ./configure; make && make install - Copy all *.LBX files from the original Master of Orion II to the installation data directory (
/usr/local/share/openorion2by default) - Run
openorion2
Further work needed:
- Analyze the rest of the original savegame format and a few remaining data files.
- Implement most of the game. The open source engine currently supports only loading saved games from the original version and viewing the galaxy map, fleet management and list of known planets.
Hack Week 19 - Signus: The Artifact Wars
Signus is a Czech turn-based strategy game similar to Panzer General or Battle Isle series. Originally published in 1998 and open-sourced by the original developers in 2003.
How to install & play:
- Clone the Git repository
- Run
./bootstrap; ./configure; make && make installin bothsignusandsignus-datadirectories. - Run
signus
Further work needed:
- Create openSUSE package
- Implement full support for original game data (the open source version uses slightly different data file contents but original game data can be converted using a script).
Looking for hackers with the skills:

It would be hard to find a game with expired copyright. But I have some recommendations: Hungry Horace Colony

Copyright status of the original game doesn't matter. We just can't bundle the original game data with the open source engine and if we need to disassemble the original EXE files, we'll need to do a "clean room" implementation of that part of the code. (One person analyzes the disassembled code and writes a spec, another person implements the spec without looking at the disassembled code.)
The games I had in mind were something like Jagged Alliance, Battle Isle 3, Polda, etc.

My top pick this year: Petroglyph has released the original sources of Command & Conquer and Red Alert as mod SDK under GPLv3. Let's write an SDL front-end for it and make the classic C&C games fully playable again. (Yes, I know OpenRA exists but I'm not installing the Mono bloatware to play it. The original game used to run smoothly on Pentium 90 with 16MB of RAM dammit!)

My second pick: Jagged Alliance 1. No sources are available AFAIK, we'll have to reverse engineer it from scratch. We might find some reused AI and game mechanics code in Jagged Alliance 2 sources though.

My third pick: Master of Orion 2. Two of our colleagues have tried to remake the engine in Python a while ago but I'd prefer to start from scratch in C++.

Nice one. I would love to see Battle of Britain - Their Finest Hour resurrected from 286 days, especially the campaign mode. Or the Wing Commander series. But these graphically oriented games are probably not doable.
Strategy games might be more within reach. I made a start on the logic of Capitalism in Golang several years ago. Basis was observed game behavior. I might still have the code lying around somewhere. Paired with a web UI, it might make a nice multiplayer (e.g. the Rancher stack with vue.js).

Thanks for the tip, I'll definitely keep Capitalism in mind for the next year. There already is a fan remake of one of the Wing Commander games: Privateer: Wing Commander Universe. Though I don't know whether it's playable and how closely it resembles the original Privateer.

My top pick this year is obviously to continue working on Master of Orion II. We've started from scratch during the last Hack Week so most of the work was about internal code infrastructure and reverse engineering with very little to show at the end. But that work is now mostly done and we can start making some big visible progress this year.
- Easy tasks: implement planet list screen, colony list screen, fleet list screen
- Medium tasks: implement colony screen, officer pool screen, diplomacy screen, audio subsystem
- Hard tasks: reverse engineer ship design, research or the rest of savegame format, implement help/info screen, find palettes for space combat sprites

My second pick this year is to select one existing open source game project from Open Source Game Clones database and contribute to it. Something semi-playable would probably be the best choice but the only real restrictions are the project licence, programming language and access to the original game files. Note that in this case we have to pick a project at least a week before the Hack Week starts so that we can look around the codebase beforehand. I don't want to spend the whole Hack Week just looking for actual issues to fix or missing features to implement.
I also have a third pick but I'll need to resolve some potential licence issues with the original developers before I say more. Stay tuned.

My top pick for Hack Week 22 is once again to continue working on Master of Orion II. We've implemented planet list and fleet list screens during the last Hack Week and both are almost feature complete except for actions that change the gamestate (which is intentional for now).
- Easy tasks: implement colony list screen, officer pool screen, diplomacy screen or fleet window (on galaxy screen)
- Medium tasks: implement colony screen, audio subsystem, ship detail window, reverse engineer ship design or research
- Hard tasks: reverse engineer the rest of savegame format, implement help/info screen or star system window (on galaxy screen), find palettes for space combat sprites

My second pick is to contribute fixes and improvements to OpenGothic. You can pick some task from the project issue tracker or play the game over the holidays until you find some bugs/missing features you'd like to fix. My personal focus would be on improving Gothic 1 support but feel free to work on Gothic 2 as well.

Just like the last time, my top pick for Hack Week 23 is to continue working on Master of Orion II. We've implemented office list screen and part of the colony list screen during Hack Week 22.
- Easy tasks: Finish colony list screen, implement diplomacy screen, research selection window, fleet window (on galaxy screen) and star system window (ditto)
- Medium tasks: implement colony screen, audio subsystem, ship detail window, colony production screen, reverse engineer ship design or planet orbit position calculations
- Hard tasks: reverse engineer the rest of savegame format, implement help/info screen, find palettes for space combat sprites

My second pick is to improve the Linux port of Gates of Skeldal. IIRC the game engine needs to be ported to LibSDL 2.0, savegame format needs some fixes and there are a few graphical glitches.

My top pick for Hack Week 24 is once again Master of Orion II. Last time, I've implemented the research selection window. The colony list screen partly implemented during Hack Week 22 remains unfinished. But there are still many more tasks to work on:
- Easy tasks: Finish colony list screen, implement diplomacy screen, fleet window (on galaxy screen) and star system window (ditto), game settings window or galaxy screen windows (opened by clicking the sidebar)
- Medium tasks: implement colony screen, audio subsystem, ship detail window, colony production screen, reverse engineer ship design, planet orbit position calculations or galaxy screen zoom buttons
- Hard tasks: reverse engineer the rest of savegame format, implement help/info screen, find palettes for space combat sprites

My second pick is to add improvements to Signus (from Hack Week 19). Implement support for subtitles in cutscenes, implement single-click "move and shoot", allow unloading transported units to a specific tile, start working on custom scenario editor (which will require redesigning the map file format and implementing more general AI algorithms).
