How to Become an Achievement Developer
This document describes all the steps that any aspiring achievement developer must follow before getting Developer status. These requirement are also a checklist for Code Reviewers (developers who inspect the code of new developers).
Anyone can become a RetroAchievements developer if they put in the effort.
Strongly recommended: join our Discord server so you can get in contact with other achievement developers who can show you the ropes and help you along. If you already know what game you want to work on, go ahead and ask for the
jr-dev role in
#tech-support forum by creating a post tagged as
Join Team and pinging
@QA-Maintainer (Make sure to first get your account verified by following instructions in
#welcome if you haven't already). This gives you access to the
#jr-devs channel, where you can talk to code reviewers and ask any development related questions.
Finding a Game to Work onlink
Follow the guidelines on the Developer's Code of Conduct to find a game to work on achievements for it. The basics are that you must declare you plans to work on the game on in the forum, and then as you work on the game, add your plans for the game in the forum.
Tip: for your first achievement set it's recommended to choose a game that doesn't yet have achievements and is not very popular.
Planning your Achievement Setlink
Once you find a game to work on you need to plan your Achievement Set.
Be sure you know enough about the game to make a good set. Check the GameFAQs or something, try to learn more about the game, its secrets and details. Here is a good guide to help you with this: Set Development Roadmap.
Post your plans on the official game's forum topic, so the community can leave suggestions and provide feedback. This is required behavior for all devs and jr-dev.
IMPORTANT!: be open to receive feedback and suggestions.
See also: Achievement Design, it's an extensive guide on how to design good and interesting achievements. It's not about the technical side but the conceptual.
Every developer must know at least the basic concepts and techniques shown in these two docs:
Any aspiring dev must demonstrate understanding of the following concepts:
- Basic RAM digging (be familiar with the Memory Inspector)
- Hexadecimal notation
- Delta values
- Hit counts
- Pause If
- Reset If
- Alt Groups
- Memory sizes: 8-bit and single bit
- Achievement logic comparisons besides
=, such as
- Adding badges to an achievment
- Creating accurate descriptions for achievements
- Add appropriate protections
- Make a stable achievement set
Note: You do not need mastery of all these concepts to have a set published, but you do need them to have the full Developer role.
Here is a list of some advanced concepts/techniques. They are not required to become a Developer, but are listed here to let the jr-dev know the possibilities of the Achievement's logic.
- Hit count as timer (like in this example and this one)
- ResetIf Checkpoints
- ResetIf with Hitcount
- PauseIf with Hitcount
- AddSource and SubSource Flags
- AddHits and SubHits Flag
- Increment counter (
Mem > DeltaCounter)
- Delta Hit Counter, pause technique
- Little endianness
- Memory size: Lower4, Upper4, and 16-bit, 32-bit
- Dynamic Rich Presence
- Pausable Resets
- SubSource increment counter
The Real Examples and Achievement Templates pages are useful resources to see how those techniques work.
Junior developers can create and delete code notes that they have created, but they cannot delete or edit any notes created by others. Developers CAN edit and remove notes by other users, and these changes are site-wide.
In order to become familiar to those techniques you must practice. You can use any game to practice, even those that already have achievements. Just be aware about these rules:
Do NOT delete/overwrite any existing Code Note.
On this practicing phase, keep your work in local and do NOT upload any achievement. You'll do it later when you find a game to actually work on.
Get your work reviewedlink
After creating some achievements, upload them to Unofficial and then create a post in
#jr-dev-forum on our Discord server (if you don't use Discord, send a message to RAdmin) and ask them to find someone to review your work.
Do NOT ask another developer to promote your achievements to the Core without a proper review.
Again, it's extremely important that you are open to receive constructive criticism and helpful advice from the community at any time.
Am I ready to get the Developer status?link
Once the Code Reviewers have inspected your achievement's code and concepts, they and the admin will use the "Required Knowledge" checklist above to determine if you're ready. If you're not fully qualified to be a developer yet, but your set is complete and stable, the set will get published. You can then ask which concepts you still need to demonstrate proficiency in to be given developer status.
The merit of a jr-dev receiving developer status depends on:
- their ability to publish work that meets the standards of the Developer's Code of Conduct;
- demonstration of required knowledge and advanced concepts;
- the quality and complexity of their work;
- the time and thought they put into planning and working on achievements;
- showing the will to use the Developer status with care and responsibility;
- the extent to which the points above reflect their capabilities as a developer.
Developer's Code of Conductlink
Once you get your Developer status, you MUST adhere to the Developer's Code of Conduct. That is extremely important to create a fair environment between the Achievement Developers.
