In 2021 the answer was easy: if you wanted a Switch controller’s gyro in an emulator on Windows, you installed BetterJoy, because there was barely another way. In 2026 the landscape has quietly reorganised itself around the program. Steam learned to speak Joy-Con. Cemu and Dolphin learned to read motion natively through SDL. And BetterJoy itself has not changed — the original still sits at v7.1, dated 22 November 2021. So the honest question is no longer “how do I install it?” but “does my setup still need it at all?” This page answers scenario by scenario. If your scenario says no, believe it, and enjoy the simpler setup — we would rather lose the install than waste your afternoon.
What actually changed
- Steam Input grew up. Pro Controller support dates to 2018; Joy-Cons — individually and combined into pairs — arrived in August 2022, gyro included, inside Steam’s ecosystem.
- Emulators went native. Cemu 2.6 reads gyro through its SDL controller support (“Use motion”). Dolphin’s own wiki now recommends SDL motion mapping over the DSU route for Switch controllers, citing lower latency.
- BetterJoy stood still. v7.1 (2021) remains the original’s final release; the repository is not archived, and a community fork carries development forward — but nothing about the original’s feature set has expanded into the territory the platforms above absorbed.
What did not change: nothing native replaced BetterJoy’s DSU/Cemuhook motion server as a general-purpose utility, nothing native gives you system-wide XInput/DS4 translation outside Steam, and one documented emulator requirement still names BetterJoy outright. Those three holdouts are the “yes” column below.
The scenario matrix
| Your scenario | Still need BetterJoy? | The route instead / why |
|---|---|---|
| You play Steam games with a Pro Controller or Joy-Cons | Probably not | Steam Input covers both natively, gyro included — the full comparison |
| Cemu 2.6 with gyro aiming | Optional | Native SDL motion first; BetterJoy DSU is the fallback when SDL detection misbehaves — Cemu guide |
| Dolphin 2609 | Optional, leaning no | Dolphin’s wiki prefers SDL motion; DSU remains available — Dolphin guide |
| Ryujinx-family emulation with two Joy-Cons and independent per-hand motion | Yes | The Ryujinx README itself requires BetterJoy or DS4Windows for dual-Joy-Con motion — Ryujinx successors guide |
| Switch emulation (Eden and relatives) with a single pad | No | These emulators model the controllers themselves; motion is native — Eden guide |
| Non-Steam PC games: Game Pass, Epic, GOG, standalone .exe titles | Yes | Nothing else gives you a system-wide virtual XInput/DS4 pad for free |
| Gyro aiming the Windows mouse / desktop | Yes | Gyro-to-mouse is a BetterJoy speciality — gyro as a mouse |
| Joy-Cons as two separate vertical pads outside Steam | Yes | Join/split management is BetterJoy’s home turf — using Joy-Cons as one controller |
| You already run DS4Windows for PlayStation pads | Maybe not | It reads a Pro Controller and serves DSU too — the DS4Windows comparison |
| Switch 2 Joy-Con 2 / Pro Controller 2 | Neither helps | v7.1 does not support the new controllers’ different Bluetooth protocol; no mapper in this series changes that |
Two footnotes people always ask about
The maintained fork changes nothing in the matrix
BetterJoy also exists as an actively maintained community fork (the d3xMachina line), which modernises the stack — current .NET, HidHide instead of the retired HIDGuardian, the final ViGEmBus — while keeping the same DSU server and Joy-Con behaviour. It matters for how you install BetterJoy in 2026, and we cover it separately; it does not change whether you need it. Every “yes” above is a yes for the tool in either lineage, and every “no” is a no for both, because the scenarios turn on what Steam and the emulators learned to do natively, not on which BetterJoy build you run.
Switch 2 controllers are a separate question
Joy-Con 2 and the Switch 2 Pro Controller use a different Bluetooth protocol — a custom BLE arrangement rather than the original controllers’ standard HID behaviour, with the Pro 2 expecting a proprietary activation exchange before it sends input at all. v7.1’s device list predates them and cannot be patched into supporting them by configuration. On PC, the only official-path progress so far is Steam’s wired (USB) support for the Switch 2 Pro Controller, which arrived in beta in late 2025. If your pad is a Switch 2 pad, no verdict in the matrix above applies — you are waiting on platform support and community projects, not choosing between mappers.
The real costs of keeping it (small, but nonzero)
BetterJoy asks three things of you: a one-time ViGEmBus driver install (the driver is end-of-life but working — our ViGEmBus repair guide covers the failure mode), a background program running while you play, and a little discipline about double input when Steam is also in the room (the fix, if you meet it). None of that is heavy. It is simply no longer worth paying for scenarios the platforms have absorbed — which is why the matrix, not habit, should make the call.
The 20-second decision flow
- Everything you play is in Steam? → Steam Input only. Done.
- Your emulators read your pad’s motion natively (try SDL first in Cemu/Dolphin)? → Skip BetterJoy until something misbehaves.
- Dual Joy-Con independent motion, non-Steam system-wide output, or gyro-to-mouse? → Install BetterJoy from the download page and configure the one mode you need.
- Still unsure where your case lands? → The best way to use a Switch controller on PC compares every route, including the paid mapper (reWASD) and the adapters (8BitDo, MAGIC-NS 2).
Verdict
BetterJoy in 2026 is not a default install and not a museum piece; it is a specialist that kept three jobs the platform holders didn’t take: DSU motion serving, system-wide translation outside Steam, and Joy-Con pair choreography. If your gaming touches any of those, you still need it — and it’s still free. If it doesn’t, the most honest advice a BetterJoy site can give you is to run the simpler setup. Either way, the Platforms & Emulators hub and the comparisons hub will walk you through the route you picked.
