Program a Cronus Zen from your browser
What’s in the video
Five steps, start to finish
Open the Studio in your browser
Go to cronuszens.com on a computer, in Chrome, Edge or Opera. Those are the browsers that can talk to a Zen over USB; phones, Safari and Firefox cannot. There is nothing to download and nothing to install.
Check your firmware
New scripts need recent firmware, so check yours once before your first script. Plug the Zen into this computer with its USB cable, press Connect your Zen in the Studio, and choose it in the window the browser opens. The Studio then shows the firmware your Zen has, for example Firmware 2.2.0. Open the Updater and follow its steps: the newest version is marked Latest. If that is the one you have, there is nothing to install. If not, install it there. It takes about a minute: keep the Zen plugged in until it says it is done.
Open the UpdaterSkip it if your Zen already has the Latest.Choose a script and press Program
In the Studio, with your Zen connected, choose a script for an empty slot, then press Program: that is the moment the script is written to the Zen. If you have just updated the firmware, press Connect your Zen again first. The Zen holds up to 8 scripts, one per slot, and you switch between them on the Zen itself.
Nothing is written to your Zen until you press Program.Connect the Zen to your console
Plug the Zen’s CONSOLE/PC port into a USB port on the console, then plug your controller into A1 or pair it wirelessly.
Check the script menu
Load into the game and open the script menu with the button combination named in the script post. That confirms the script is running rather than just installed.
Install a script without Zen Studio
To program a Cronus Zen without Zen Studio, use the Cronus Zens Studio on cronuszens.com: plug the Zen’s PROG port into a computer with a data cable, open this site in Chrome, Edge or Opera on Windows, Mac, Linux or ChromeOS, sign in with Discord, choose a script for a slot and press Program. Nothing is downloaded or installed, and you do not need Collective Minds’ Zen Studio desktop app, which is for Windows and macOS.
Collective Minds’ Zen Studio keeps one job: setting the output protocol for Xbox, PS4 or Switch, which also works in their Zen Studio in Chrome, a separate tool from ours. Close it before you connect here, because the Zen opens in one app or tab at a time.
Some of our scripts on Collective Minds are locked and open with a code. Get the code at cronuszens.com/key, then type it on the Zen’s code screen.
Check your firmware in the Updater first. It installs the latest build from the browser too.
Then set the Zen up for your console: PS5, PS4, Xbox or Nintendo Switch.
Connecting your Zen to a PC or Mac
How do I connect a Cronus Zen to my PC?
Plug the PROG port, on the side of the Zen, into the PC with a USB data cable. Open this site in Chrome, Edge or Opera, press Connect your Zen and pick the Zen in the browser’s list, where it may be called Cronus Bridge. The CONSOLE/PC port on the back goes into the PC only while you update the firmware in the Updater. A charge-only cable powers the Zen, but the PC cannot see it. How to connect a Cronus Zen to your PC has each step.
Can I set up a Cronus Zen on a Mac?
Yes. The Studio works in Chrome, Edge or Opera on a Mac, the same as on Windows, Linux and ChromeOS. Safari cannot reach a Zen, so use one of those three.
Can I put scripts on a Zen without a computer?
No. Programming needs Chrome, Edge or Opera on a computer; phones, tablets, Safari and Firefox cannot reach a Zen over USB. Once a script is on a slot, the Zen runs it on your console with no computer attached.
Why does the Studio not find my Zen?
Close Collective Minds’ Zen Studio and any other tab using the Zen, check the cable carries data and is in PROG, then replug and press Connect your Zen again. Zen not detected covers the rest.
When it does not work
The controller does not respond after plugging in the Zen
CONSOLE/PC goes to the console and your controller goes into A1. PROG is only for programming from a computer, so a Zen plugged into the console through PROG passes nothing through.
The script compiles but nothing happens in game
Check that the slot you programmed is the slot the Zen is actually on. Press the button on the device to cycle slots, and confirm the script menu opens on your controller.
Timing feels off
NBA 2K scripts are tuned to a build height, so a script set for one height will be early or late on another. Set the height in the script menu to match your build.
The console disconnects the controller randomly
Use a wired connection between the controller and the Zen while you are testing. Wireless pairing through the Zen adds a failure point that looks like a script problem.
Still stuck? Open Support Chat, or ask in our Discord. Say which step you are on and what the Zen did.

Using Linux? Read this if the Zen won’t open
Only for Linux. On Windows or a Mac, skip this.
The Studio works on Linux, and it is the only way to write to a Zen there at all, since Cronus’s desktop Zen Studio app is Windows and macOS only. One thing is in the way. Linux creates the device owned by root and grants nobody else access, and nothing in the standard rules covers a device like the Zen. So the browser can list it in the picker and still be refused the moment it tries to open it, which reads as the site being broken when it is a permission that has never been granted.
Confirm it is a permission problem
Open chrome://device-log in another tab, then come back and press Connect. If the log says FILE_ERROR_ACCESS_DENIED against a path like /dev/hidraw3, this is it, and that path is the device you are about to grant access to.
Check how your browser was installed
Run: snap list | grep -i chrom. If that finds your browser, stop here. A Snap browser is sandboxed away from these devices before file permissions are even looked at, and no rule can reach it. Install Chrome from the .deb or .rpm instead. Flatpak is fine and needs nothing special.
snap list | grep -i chromAdd the rule
Create /etc/udev/rules.d/70-cronus-zen.rules containing the single line below. The 70 matters: the rule that acts on this is numbered 73, and udev reads files in order, so the usual 99 prefix would add the tag after the only thing that reads it and change nothing.
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{idVendor}=="2008", ATTRS{idProduct}=="0010", TAG+="uaccess"Apply it, then replug
Run the two commands below, then unplug the Zen and plug it back in. The replug is not optional. Reload the Studio afterwards.
sudo udevadm control --reload-rules sudo udevadm trigger --subsystem-match=hidrawCheck it worked
Run getfacl on the device path from step 1. You want a line reading user:yourname:rw-, with the rw spelled out: read on its own leaves the Studio connecting and then failing mid-write. Note that ls -l still shows crw------- here, and that is correct. The trailing + is the only visible sign, and the permission itself lives in the access list rather than in those bits.
getfacl /dev/hidraw3
Two notes, because both cost people real time. The rule Chrome’s own documentation prints uses a group called plugdev, which does not exist on Arch, Fedora or openSUSE, so it silently does nothing there. And the rule on the Cronus site is for the device in firmware update mode, which is a different identity to the one it uses the rest of the time, so it will not help here.
Video transcript
Cronus Zens 2K in the video is now called cronus2K. A correction on the code: the seasonal codes (Halloween in late October) take 15% off the Club for as long as you stay. For cronus2K, add 10 to the same code, for example HALLOWEEN10, for 10% off. The Shop page shows the current one.
Connect your Zen
0:00Setting up your Zen only takes about a minute, and you do it all from cronuszens.com. Plug your Zen into your computer with a USB cable. Then open the Studio and press Connect your Zen. The first time, you’ll sign in with Discord. Then your browser shows a list.
Choose a script for each slot
0:13Pick Cronus Zen, press Connect, and you’re in. Now choose a script for any of the eight slots. Your Zen holds up to eight, one per slot. I’m putting yew2K on slot one, then grabbing Fadeaway from the NBA 2K27 library for slot two.
Add cronus2K and program
0:27For Cronus Zens 2K, head to Download. Pick your build, set your build height, and it shows you your green window. Then choose slot three and add it. Press Program and it writes every slot in one go. Once it says your Zen is programmed, unplug it from your computer. Plug the Zen into your console and your controller into the Zen.
Switch slots on the Zen
0:45Then press the button on the Zen to switch between your slots. That’s it. Cronus Zens 2K is a one-time purchase, and code Halloween gets you 15% off forever. The link is in the description. And if you’ve got any questions, hit us up.
Where to go next
Every script on this site is programmed to a slot from the browser, so once the Zen is on current firmware there is nothing else to install.
