SeventhSentinel--err I mean, Sonic explains the v1.1 patch update


This game has absolutely no single player content outside of time attack. There are no CPU players. To get the full experience, you have to rely on either splitscreen or online multiplayer. As with most games, hosting games will require port forwarding. The port to forward here is 5029, UDP.

It should be noted that this game has absolutely no clientside prediction whatsoever, and runs on a fairly antiquated client/server networking model. It's extremely likely that you will experience latency in some form. Make sure you join servers that you have a low ping to, even if another server has more players. This will help create a better experience for players across many different regions.

Now without further ado, in Sryder's own words...


SRB2Kart is a classic styled kart racer, complete with beautiful courses, and wacky items. Of course, because it’s SRB2Kart, it has a Sonic twist that really shows the classic charm that a lot of us know and love from the good old days™.

We have 100 jam-packed maps for you to bump, explode, and sparkle your way through, from luscious beaches, to Eggman’s dance floor, to England on a good day. All lovingly crafted by many different people. You’ll notice almost every aspect of the game has an immense love and inspiration from the classic sonic games. From the items such as Ballhog, which literally throws bouncey explodey balls at people, to the maps which are bursting with that Sonic feel.

Of course, you'll only start off with a few cups available, but you can unlock more by playing offline/online matches. Alternatively, you can immediately jump into challenging yourself and race us personally in Staff Attack mode! Don't worry, we'll go easy on you.

Game Modes
We have 2 game modes for you to choose from: Race, and Battle.
Race mode is the normal: Race through the track to beat your opponents, use your items and skill to swooce past the competition, Oh my God what is that following behind me HELP! You know, the usual.

Battle mode asks you to violently throw spikeballs at your friends until they have no bumpers and you have some. But watch out, they can come back with a vengeance and chase you to the ends of the earth afterwards! Or maybe if they’re feeling nice they might help you with a powered up item

As you’ll find, we have 5 characters in the base game to enjoy, all with very distinct stats. Before we go into them individually, I’ll explain how our stats work. We have separate variables that effect the way a character plays. Speed, and Weight. Higher speed gives you a greater top speed, but sacrifices your ability to accelerate, higher weight reduces your control over your drifting, but you bump players that you are heavier than more violently. Your combination of speed & weight decide how fast you earn drift sparks. We have this shown clearly on a handy dandy grid on the character selection screen in the main menu, pick the character that aligns with your desires most!


Sonic is just what you’d expect from our favorite blue hero! Pretty fast and agile! He’s got some good speed, and can control his drifts pretty well, just make sure you get the drift boosts because otherwise you’ll fall behind!


Our cute fox boy Tails! Tails has slow speed, but can really get going quickly, he can also take incredibly tight turns all the time, get close to those corners for him to really slip past people!


Here he comes, tougher than the rest of them. Knuckles is average in both stats, he’s very balanced, and likely a good pick if you don’t know who to try first!

Dr. Eggman

Ohohohohoho! Eggman has come along to steal the competition! He’s quite slow though, so take advantage of his fast drift-spark rate and his immense weight to stop others from overtaking!

Metal Sonic

*Loud Angry Robot Noises* Metal Sonic is fast, and heavy. He’ll fly through the courses if given the chance, but his cornering leaves much to be desired…

Bonus Ducks Characters
Included with the main download is bonuschars.kart. We don’t add it by default, but you can easily do so from the add-ons menu for many more characters to play with! A slew of extras, by a trio of our other devs in their free-time, as well as a few Community artists!

The Various Other Things
-Make sure to check out the in-game manual by pressing F1 or using the menu if you need some help or tips!
-We’ve added some extra Quality of Life features from the vanilla game to help out, such as multi-admin and a chat system that is readable!
-There’s a slight lack of documentation for modding currently, we’ll try and get on that as soon as we can.

We plan to redo the crediting in some fashion eventually so all the track sources can be included in-game, but until then they'll all just be right here for very easy viewing!

If you don't have the game, then you want the Full Install. If you already have v1.1 or higher, then you might want to use the Patch to save on download size, but it is otherwise functionally identical to using the full installer on the same folder.

Full Install (Windows)

Patcher (Windows) (For version 1.3)

Full Install (Mac)

SRB2Kart now uses an APT repository via Launchpad for handling Linux editions. Your add-ons and data will be saved in your home folder (~/.srb2kart). To view information about each install package, visit our Launchpad PPA page:

Debian users will first need to use these commands to retrieve the repository public key:
$ sudo apt-get install dirmngr
$ sudo apt-key adv --keyserver hkp:// --recv-keys BC359FFF5A04B56C41DBC134289CABAB043F53A7

Next, Debian & Ubuntu users can run these commands to install the game.
$ sudo add-apt-repository ppa:kartkrew/srb2kart
$ sudo apt-get update
$ sudo apt-get install srb2kart

If Terminal does not have a "add-apt-repository" command, then also enter:
$ sudo apt-get install software-properties-common

These instructions are largely identical to base SRB2's, just switched out repo & package names. For more detailed information, visit this page:

The changelogs for every single update can be found here:

MANUAL (F1 in-game)

The non-Windows builds are experimental and haven't been tested nearly as much; if you have issues, you can always attempt to compile it for yourself on your own computer:

I V E B E E N W A I T I N G F O R T H I S.

Gonna try this out as soon as I get home.




Keeping it classic
YEEEEEEEEEEEEEEEEEEEEEES. You all have no idea how long I've waited for this. Congrats on all the hard work put into this release.


aka J-town/NeonJ
It's finally here...

... and by the looks of it, it plays fantastically! Can't wait to check this out on the MS.

Does things with the stuff
Hooo boy it's been ages since was first being teased. And at long last, it's finally here. I know what I'm gonna sink my time into for a while.
I've got to say, this is by far the best of the "SRB2 Racing Game Ports". It took me a bit to get used to it, but I'm already having a blast just going after the time trial medals.

Also, I dunno if this is already known, but I managed to find a pretty big shortcut for Metal Sonic (although it might barely be possible with some other characters) in MKSC Sky Gardens. Hopefully this mod gets a section on the records site, I'm really interested in seeing what other sorts of shortcuts can be taken. (I'm almost certain you could get some kind of shortcut by bouncing off those beanstalks, since I almost managed it once on accident...)

"The number of console HUD lines is now 5"
Everytime it appears, it frozes the game.


When i tried to host or join a game, it said it contained a virus and got moved to a virus chest

Prime 2.0

Momentous. As somebody who played the original SRB2Riders back before it was even an EXE mod, I know quite a bit about how far this thing has come, and after getting a controller to work and diving in properly, it's absolutely breathtaking to see this spinoff of a spinoff port stand so tall on its own two feet. Battle mode in particular was an absolute joy to play, and the bomb kart mechanic kept things engaging no matter whether I was winning or losing.

In the DooM community, a project like this would be called a Total Conversion, but while technically accurate it would be a disservice to think of SRB2 Kart in those terms. This is its own game, period.

And a damn good one if I do say so myself. Congratulations on finishing this tremendous release.
