Running Multiple Controllers Through One Cronus Zen for 2K27

Can you plug two controllers into a Cronus Zen for 2K27? Here is what the ports actually do, and where Fadeaway fits into a two-pad setup.

People ask this constantly in setup threads.

Can you run two controllers into one Cronus Zen at the same time?

Short answer: yes, but only one of them is the one the script is watching.

What the Zen's ports are actually for

The Cronus Zen has two controller-facing ports on the front: a primary port and a secondary port. The primary port is where your main pad connects, and that is the input the script reads and reshapes before sending it to the console. The secondary port exists mostly for controller-passthrough setups, like a training partner's pad or a backup controller you want ready without unplugging anything.

I checked this against the install guide before writing this piece.

VeraScripts' own setup guide, "Install a Vera script from your browser," lays out a specific sequence: connect the Zen, choose an empty slot, flash the script, then hand off to the console. Nothing in that flow mentions a second controller sharing script logic. The 5-minute read is built around one primary controller because that is the only one the flashed build is tuned for.

That single-input assumption isn't a Fadeaway quirk.

It's how the Zen platform works across every game it supports.

Why a second controller doesn't get the same timing help

Fadeaway 2.2, released September 2, 2026, tunes timing to one input stream: STAND at 600ms, MOVE at 613ms, R RUN FADE at 885, L RUN FADE at 759. Those numbers come from the primary port's button presses being read and reshaped in real time. A second controller plugged into the secondary port isn't part of that loop, so it won't get the timing assist, the Auto Go To hold, or any of the shot-router logic that separates STAND, MOVE, and run fade.

If you're playing local co-op or letting a friend hop on, their controller works the way NBA 2K27 works without a Zen at all: native inputs, no timing assist, no Button Remap.

That's a limit worth knowing before you buy, not after.

Local co-op and backup-pad scenarios

There are two real use cases people mean when they ask this question, and they get different answers.

Local co-op, both players want the timing assist active. Not possible on one Zen. The device processes one primary input for one script slot. Two players each wanting Fadeaway's assist would need two separate Cronus Zen units, each running its own flashed copy, each plugged into its own controller port on the console.

Backup pad, only one player needs the script. This works fine. Plug your main controller into the primary port, plug a spare into the secondary port as a standby. If your primary pad has an issue mid-session, swap it in without re-flashing anything.

Here's a quick reference for what each port does when Fadeaway is loaded.

Port	Typical use	Gets timing logic	Notes
Primary	Main controller during play	Yes	This is the input the script reads and reshapes
Secondary	Backup pad, passthrough device	No	Native inputs pass through untouched

What this means for a two-player household

I run a Zen on a shared PS5 at home, and the backup-port question comes up every time a second person wants to hop on 2K27.

My take: buy a second Zen if two people in the house genuinely want the timing assist, because trying to split one unit's primary input between two pads defeats the whole design.

A single Zen unit is built around one controller getting the tuned behavior.

Splitting that intent tends to cause more troubleshooting than it saves.

Slot management still matters here

Even with just one controller in play, the Zen's slot system deserves attention if you're switching between Fadeaway and something else on the same device. VeraScripts documents this in "Choose, clear, and manage Zen slots," a 4-minute guide that covers using an empty slot and preserving existing scripts rather than overwriting them. If you're testing a two-controller setup and something behaves oddly, check your slot assignment before assuming the hardware is broken.

Firmware also plays into this. Update Cronus Zen firmware through the official Cronus Web Update Tool, entering bootloader mode correctly and returning to normal mode afterward, per VeraScripts' 5-minute firmware guide. An out-of-date firmware build can cause port detection issues that look like a multi-controller problem but aren't.

What actually happens if you try it anyway

Say you plug two controllers in and just start playing 2K27 with both.

The primary pad plays with Fadeaway's tuning active: the timing assist, per shot type, and GLOBAL adjustment for online delay.

The secondary pad plays raw. No timing help. No Button Remap. Just the console reading its inputs directly, same as if no Zen existed for that pad.

For couch co-op against the CPU or friendly local games, that's often fine. One player getting the assist in a friendly local match isn't the same conversation as ranked play, and the split just reflects how the hardware is built, not a workaround.

Where GLOBAL fits into a shared setup

If you do rotate the primary port between two people, remember that GLOBAL is a personal setting, not a universal one. VeraScripts' guide "GLOBAL: the one setting you change online" is a 3-minute read that explains this exactly: GLOBAL shifts every shot type at once to compensate for online delay, and it's meant to be nudged up if timing lands early, down if late.

Two different players will likely need two different GLOBAL values.

If you swap the primary controller between people during a session, expect to re-tune GLOBAL each time, not just once.

A note on install time and where this fits the bigger picture

None of this changes the install itself. Fadeaway still flashes from the browser in about a minute, per the setup guide, and settings carry forward through dual-bank writes so tuning survives future updates. The two-controller question sits outside that flow entirely. It's a hardware-routing question, not a script-tuning one.

Where to go next

If you're setting up Fadeaway for the first time, start with the official page for specs and pricing: Fadeaway on verascripts.com, $50 one time covering the 2K27 season with updates included. Pair it with the setup guide before you touch a second controller, so you know exactly what the primary port is doing.

Frequently asked questions

Can I plug two controllers into one Cronus Zen at the same time?

Yes, physically. The Zen has a primary and a secondary controller port. Only the primary port's input gets read and reshaped by whatever script is flashed, so a second controller in the secondary port plays without the timing assist or Button Remap.

Will a second controller get Fadeaway's timing assist too?

No. Fadeaway 2.2 tunes one input stream: STAND at 600ms, MOVE at 613ms, plus the run fade values. That engine reads the primary port only, so a second pad plugged into the secondary port plays 2K27 natively.

Do I need a second Cronus Zen for local co-op with the assist active for both players?

Yes, if both players want the timing assist or Button Remap active. One Zen unit processes one primary input for one flashed script slot, so getting scripted timing for two players means two separate Zen units, each with its own Fadeaway install.

Does switching the primary controller mid-session mess up my Fadeaway settings?

No, your tuned values stay saved through dual-bank writes that migrate settings forward. But GLOBAL is personal to each player's feel, so if you hand the primary controller to someone else, expect to re-tune GLOBAL rather than reuse your own number.

Is the secondary port useful for anything besides a spare controller?

Yes, it works as a passthrough for a backup pad in case your primary controller has an issue mid-game. It does not add a second scripted input; it's meant for standby use, not simultaneous scripted play.

Where do I check if my two-controller setup is behaving oddly?

Start with slot assignment using VeraScripts' 'Choose, clear, and manage Zen slots' guide, then confirm firmware is current using the official Cronus Web Update Tool per their firmware guide. Most odd behavior traces back to one of those two things rather than the controllers themselves.
