# Cronus Zen vs ReaSnow S1: what each does, where they overlap, which to choose > Cronus Zen vs ReaSnow S1: pick the S1 for mouse aim with built-in macros and the Zen for GPC scripts, which the S1 cannot run, compared feature by feature. - Canonical: https://cronuswiki.com/docs/cronus-zen-vs-reasnow-s1 - Site: Cronus Wiki (https://cronuswiki.com/) - Author: Cronus Wiki Editorial (https://cronuswiki.com/authors/editorial) - Section: Comparisons - Published: 2026-09-23 ยท Updated: 2026-10-07 - Tags: reasnow s1, comparison, mouse and keyboard, alternatives --- Choose the ReaSnow S1 if you want mouse aim with a few built-in macros, and the Cronus Zen if you want to run scripts written by someone else; the S1 does not load GPC scripts. The S1 is a mouse-and-keyboard converter first, with built-in extras such as macros and mapping, but no open scripting. If you want mouse aim with a few conveniences, it is a candidate. If you want to load a seller's or the community's script, it is not. ## What each one is | | Cronus Zen | ReaSnow S1 | | --- | --- | --- | | Maker | Collective Minds | ReaSnow | | Purpose | Scripting device with M&K mode and crossover controllers | Converter built around M&K, with built-in extras | | User scripts | GPC, GamePacks, eight 32 KB slots | None | | Built-in features | Via GamePacks and scripts | Macros (including an anti-recoil type), button mapping, in its app | | Configuration tool | Zen Studio Live in a browser, or the legacy desktop Zen Studio | ReaSnow's app | | Other inputs | Controllers, mouse, keyboard, older Logitech and Fanatec wheels in Wheel Mode | Controllers, mouse, keyboard, wheels, flight sticks | | Authentication | A matching pad on A1 for crossover on Xbox and PS4; none on PS5 or Switch | See ReaSnow's manual for your console | | PS5 | Zen Link module (PS5 Native Mode), the route Cronus recommends; or a manual bypass that has to be repeated | Listed by ReaSnow; check its current method | | Xbox Series, PS4, Xbox One | Yes | Listed by ReaSnow | | Switch | Yes, Switch, OLED and Lite; not Switch 2 | Listed by ReaSnow | ## Where they overlap | Feature | Zen | ReaSnow S1 | | --- | --- | --- | | Mouse to right stick | M&K mode; tune sensitivity, curve, boost and deadzone | ReaSnow's mouse engine and curve editor | | Anti-recoil | Any script's table, per weapon, per attachment | A built-in anti-recoil macro type with values you set | | Macros | Any script | Built-in macros, editable in the app | | Remapping | Any script, the M&K layouts, and Zen Studio's remapper | In the app | | Rapid fire | Any script | As a macro | The overlap is real for a player who wants mouse aim plus a fixed anti-recoil value and a macro or two. The S1 does those inside its app without a script. ## Where they differ | You want | Zen | ReaSnow S1 | | --- | --- | --- | | A shot-timing script for NBA 2K | Yes | No script support | | A seller's script that updates after each patch | Yes | No | | Anti-recoil that switches with weapon and attachments | Yes, in a script | Values you set yourself | | A GamePack with a settings menu | Yes | No | | To write your own logic | Yes, GPC | No | [How the Cronus Zen works](/docs/how-the-cronus-zen-works) covers what a script adds that a fixed feature cannot; [Mouse and keyboard on the Zen](/docs/cronus-zen-mouse-and-keyboard) covers the Zen's M&K mode in detail. ## Consoles On Xbox and PS4, the Zen needs a pad that matches the console on A1 whenever you play on a mouse, a keyboard or another console's pad; on PS5, Cronus's current guide recommends Zen Link, which gives PS5 Native Mode with a one-time setup, and describes the bypass that works without it as a manual procedure that has to be repeated ([PS5 setup](/docs/cronus-zen-ps5-setup)). ReaSnow lists the PS5, Xbox Series, Switch and older consoles as compatible with the S1; its own manual and notes are the authority for how each connects, and this site does not track them. ## Risk Identical in kind. Both produce input patterns a thumb cannot. Activision says its 2026 detections look at how inputs behave, not which device is plugged in, and Respawn's 4 March 2026 statement covers "Strikepacks, Cronus, XIM, and similar hardware that manipulate input behavior". Neither post names the S1, and neither needs to. [Is the Cronus Zen detectable?](/docs/is-the-cronus-zen-detectable) applies to the S1 equally. Nothing on this site describes either as undetectable. ## Which to buy | If | Buy | | --- | --- | | Mouse aim, one anti-recoil value, a macro or two | ReaSnow S1 | | Any script written by someone else | Zen | | NBA 2K | Zen | | Call of Duty with per-weapon tables that update after patches | Zen | | Mouse aim above all, scripts never | Compare the S1 with the [XIM Matrix](/docs/cronus-zen-vs-xim-matrix) | | Not sure | Zen; it does the S1's job, less elegantly, and everything the S1 cannot | [Cronus Zen alternatives](/docs/cronus-zen-alternatives) puts the S1 next to the whole field.

GPC scripts and GamePacks are for the Zen. **Which is better for mouse and keyboard?** There is no published side-by-side test to cite, and this site has not measured one. ReaSnow builds the S1 around mouse optimisation; on the Zen, M&K is one feature among many, tuned in its M&K Settings panel. **Does the S1 work on PS5?** ReaSnow lists the PS5 among compatible consoles. Check ReaSnow's current notes for the method and console version you are on; this site does not track it. **Which is easier to set up?** For M&K only, the S1 is the more focused device, with fewer settings to learn. For anything involving a script, the Zen, because the S1 cannot run one. **Are both detectable?** Neither is undetectable. Activision says its detections look at how inputs behave rather than which device is plugged in, and Respawn's ban statement covers 'Strikepacks, Cronus, XIM, and similar hardware'.
