So, you wanna post a mod you've made? Submissions is where it goes!

When you post mods in Addons & More, a corresponding thread is created here. A judge will check your mod, and if it follows all rules and guidelines, then the mod will be approved, and its thread will be moved into its proper place in Addons & More Discussion. If there is something wrong that needs to be corrected, then a judge will inform you of what needs to be done. Once you've made the requested changes, you must re-submit your mod, and it will be evaluated again. If you don't meet the requirements or continue to not follow the instructions given, then your mod will be moved to Rejected Submissions.

You can only see your own submissions, and only judges and moderators can see all the submissions. Submissions will remain hidden until they are moved to Addons & More.

Addons that do not follow these guidelines will most likely be rejected, however that doesn't always mean you cannot share them on the MS or in the community.
Please refer to the
Message Board Rules, Discord Server Rules, or the Master Server Hosting Rules to know what is and is not allowed on each platform.
If you are confused, please contact the Staff responsible for the platforms you need support with.

Mod Submission Rules
  1. Message board rules apply to all submissions, particularly concerning bigoted or inappropriate content.
    • Example: If your file contains pornographic content, it will be rejected.

  2. File names must conform to Filename Conventions.
    • Example: A file named “myzone.pk3” will not pass, but a file named “SL_myzone_v1.pk3” may pass.

  3. Your submission must have a good chunk of content that you created yourself. There are two exceptions. The only exceptions are if you’re submitting something on behalf of someone else with their consent, or you are porting an old addon and following the guidelines set in Rule 15 (see below).
    • Example: Repacks of others’ content with nothing new added will not pass.

  4. No plagiarism! If you do not have permission to use someone else’s work in your mod, and it was not marked as Open Assets, it will be rejected.

  5. Credit and Link any Open Assets! If your mod uses anything marked as Open Assets, you must credit its author and provide a link to it in your mod's description. Even if your own mod is not marked as Open Assets, it's important to support the original work by crediting it as this makes it easier for others to discover the used addons.

  6. Please keep unorganized Kart character in a single place. We prefer that each creator keeps only one pack, but if you have enough characters, you may create additional entries for the sake of organization based on theme or mechanics (series, original characters, Lua, collaborative works, etc).
    • Example: A user creates 5 characters with no common theme, so they submit them as a single pack and update as they add more.
    • Example: Another user creates a collection of Pizza Tower characters, several of their original characters, and some characters that utilize Lua to provide interesting new driving mechanics. These could be separated into three different packs, uploaded as separate Addons & More entries.

  7. When making a kart character with Kartmaker, you should check if there aren't any name templates left behind. (Specifically talking about anything that has "EXMP" in it) You can change it to something else that represents anything related or closely resembles your character's name, it's up to your criteria but it must be four letters total.

  8. Custom colors cannot be released solo. A pack of at least 3 is acceptable. Only one custom colors mod per author is allowed.
    • Example: A single color would not make a suitable release, but custom characters can have custom colors and/or include these colors as additional downloads.

  9. Your submission must work at a basic level. Mods that immediately soft-lock or crash will not be accepted. Kart characters have some additional requirements: all icons (Mini-map, Rank, Wanted) must feature clearly visible color changing. Your character does not need full voice lines or SFX, but they must have a gloat sound, which is used for certain power-ups.
    • Example: If your addon generates errors or warnings in the console, that’s fine, but it must still work as intended. We are not your beta testers, so we don’t dig for the little details.

  10. When posting map submissions you must specify the map's gametypes.If you post a map pack you should mention the gametypes included in it.
    • If it's a Singleplayer or Race/Circuit map then it should be beatable.
    • If it's a Capture the Flag map then it should have flags from both teams included in it.
    • If the Map supports any Ringslinger-enabled gametype, then there must be a reasonable amount of normal rings available at minimum.
    • If your Map is designed for a custom gametype, then you must specify the gametype and ensure it follows the requirements outlined by the original gametype addon post.

  11. When posting 3D Models for characters, you must provide the line of text for the model.dta. This will make it easier for all users to quickly apply your models to their personal models configuration, so please be sure to include it!
    • When posting content under the Software category, you must provide the source code for it.

  12. Keep personal disputes out of your addons.
    • Example: Your addon may not break other addons on purpose or contain rude messages about other community members.

  13. If your mod is a custom build exe, has net-game support, and is incompatible in any way with vanilla SRB2 netplay then it must include a custom MODID to avoid conflicting with vanilla SRB2 net-games on the Master Server.

  14. Do not pack individual PK3s in a .zip file. PK3s are already compressed, so putting them in .zip archives does not compress them any further.
    • Example: If you want to include multiple PK3s together (such as individuals for a character pack), putting them in a .zip file is acceptable.

  15. Porting content that predates the Re-Usability/Open-Asset system is allowed under certain circumstances. See as follows.
    • If you wish to port legacy content of this type, a reasonable attempt must be made to contact the original author. A pm via the forum must be sent, and you must look for them in the Official SRB2 Discord. If you do not receive a response in at least 2 months, you can continue through the releases process. For such a release, you must credit the original author(s) in the release post, in any Lua scripts, and in all of the map headers. No exceptions.
      • If the user is active on well-known social media sites (Twitter/X, Facebook, Tumblr, Youtube, Etc.) then you should contact them there too if you don't get an answer on the SRB2 MB Forums.
    • The addon you wish to port must not have already been ported and submitted on the MB before.
      • Adding features or other changes that offer more value or authenticity to the port may allow this rule to become an exception to your submission.
    • If you wish to make any changes to the content aside from a mere port, this is allowed, but you must release an unmodified legacy variant alongside your modified version in the same thread.
      • Example: If you port an old character that had double jump as an ability, but you give it a new ability, you must release a "Legacy" port of the character with the original ability in the same post as your modified version.

  16. Do not submit recreations of others' unreleased work without permission. This includes recreating sprites, other graphics, maps, scripts, music, sound, etc seen in publicly showcased Gifs, videos, design documents, or other media. It's fine to make things with similar ideas, but if you only make that thing because you saw someone else making it first, then we can't accept it. Taking inspiration from other sources is fine, but hijacking ideas you know other people are already working hard on is extremely demotivating for people and discourages community members from sharing their WIPs, and we don't want that kind of environment.

  17. Do not directly upload content that does not belong to you. Using content from other people in your submissions is fine, as long as that content was previously released as Open Assets or you've got the author's explicit permission, and your submissions contain content you made yourself. Submitting something you do not have permission to or is just a re-upload or compilation of someone else's work will lead to instant rejection.

  18. You cannot upload music or sound effect packs solely comprised of music or sound effects you did not make, regardless of whether they're Open Assets or not. Porting or extracting music and sounds from other sources to replace vanilla sounds and music will not be accepted here.
We reserve the right to make exceptions to any of these rules where we find it justified to do so.

When posting your submission, make sure you do the following:

  1. Upload your mod files using the top Attach Files button. If your file is too big to fit, use a split .RAR or .7z file. You may have mirrors on other hosts, but the entire submission needs to be uploaded to the message board.

  2. Upload screenshots to go along with your submission using the bottom Attach Files button. Nobody's going to be interested in your modification without being able to see it first. Remember that movie mode (F9 to enable/disable) can record animated GIFs of gameplay when your modification can't be shown off by a still screenshot.
    • If you want to include full-sized images in the body of the post outside of the screenshots section, right click the uploaded picture in the attachment manager to get its URL, and then use that URL in IMG tags as normal.
    • Do not use external hosts such as Discord or Imgur for screenshots used in the release post. Using sites like Imgur for minor banner images or promotional images is fine.
    • When uploading images for use in-line inside of the post (ex: promotional images or an intro/cover image), keep in mind that if the file-size is too large transparency may break, and that you can avoid the "click to see full size" banner by keeping the width of the image under 640 pixels.
    • Please ensure that you use the the bottom Attach Files button to upload screenshots, otherwise they will appear as part of your mod's game files, which can confuse people.
Finally, please be patient. The community judges are people too and it may take over a week for your submission to be looked at. If it has been over a week with no response, please contact us using this sub-forum.
