Any controller that registers as a standard HID gamepad — which is essentially every Xbox-style controller, every PlayStation controller, every Switch Pro controller, and the entire 8BitDo lineup — works immediately with no driver install. The browser polls 16 buttons and 4 axes; the emulator core remaps them to the original console's button layout. ## Top picks Three categories — wireless, wired, and budget. - 8BitDo Pro 2 (wireless) — the best generalist controller for browser emulation. Bluetooth or USB, four programmable back buttons, Switch/Mac/PC/Android profiles, ~40 hour battery. ~US$50. - 8BitDo SN30 Pro (wireless) — SNES-styled face buttons with full analog sticks. Best for 16-bit-era games where the d-pad-first layout feels right. ~US$40. - Hori Fighting Commander (wired) — six-button Genesis-style face layout. The only modern controller built specifically for arcade and 6-button fighting games. ~US$45. - Xbox Wireless Controller — works flawlessly via Bluetooth or USB, available everywhere. The default if you already own one. ~US$60. - 8BitDo Zero 2 (wireless, budget) — keychain-sized SNES-style controller. Great for travel and the cheapest credible option. ~US$20. ## How to pair 1. Plug in the USB cable, or hold the controller’s pairing button and select it from your OS’s Bluetooth menu. 2. Open the emulator page and press any button on the controller. The browser shows the controller as connected; the emulator picks it up automatically. 3. If buttons map wrong, open the emulator’s in-game menu (usually Esc on keyboard or hold L+R+Start) and use the input remapping screen. ## Troubleshooting - If the browser doesn't see the controller, confirm it shows up at https://gamepadtester.net first. If not, the browser isn't reading it at all and the emulator can’t either. - Bluetooth latency is sometimes 8-15 ms higher than wired. For fighting games and rhythm games, prefer the wired option. - Some controllers use proprietary drivers (e.g., older PS3 controllers on Mac). Those don’t work with the Gamepad API. Stick to the lineup above to avoid the issue entirely. ## FAQ Q: Do I need a special USB cable? A: No. Any USB cable that fits the controller works. The browser communicates with the controller via the standard HID gamepad protocol. Q: Will my PS5 DualSense work? A: Yes via USB or Bluetooth — it registers as a standard gamepad. Trigger-effect haptics aren’t exposed via the Gamepad API, so you lose the adaptive triggers, but face buttons and sticks work normally. Q: Does an arcade stick work? A: Yes. Hori, Qanba, and Mayflash arcade sticks all enumerate as standard HID gamepads. ## Top picks ### 8BitDo 8BitDo Pro 2 (5/5) — $45-55 The best generalist controller for browser emulation — Bluetooth or USB, four programmable back buttons, multi-platform profiles. Our default recommendation. Plug-and-play in every browser, ~40-hour battery, switchable Switch / Mac / PC / Android profiles, and back-button mapping that compensates for emulator-quirky button layouts. Pros: - Plug-and-play in every browser via Gamepad API - ~40 hour battery life - Four programmable back buttons - Switch / Mac / PC / Android profile switching Cons: - Bluetooth latency 8–15 ms higher than wired — wired mode preferred for fighting/rhythm games ### 8BitDo 8BitDo SN30 Pro (4/5) — $35-45 SNES-styled face buttons paired with full analog sticks — the cleanest fit for 16-bit-era games where the d-pad-first layout feels right. Buy this one if your library is mostly NES, SNES, Genesis, and GBA. The SNES-faithful d-pad is unbeatable for 2D platformers and the analog sticks bridge the few PS1/N64 titles in your collection. Pros: - Best d-pad for 2D platformers - Authentic SNES-era face button layout - Compact, easy to travel with Cons: - Smaller hand-feel than Pro 2 on multi-hour sessions ### Hori Hori Fighting Commander (4/5) — $40-50 Six-button Genesis-style face layout — the only modern controller built specifically for arcade and 6-button fighting games. Wired-only, niche, and brilliant at one job. If you play Street Fighter II, Mortal Kombat, or any Genesis fighter at all seriously, the six-button face layout pays for itself the first afternoon. Pros: - Native 6-button layout for arcade fighters - Wired = lowest possible latency Cons: - No analog sticks — useless for PS1/N64 3D games - Wired-only, no Bluetooth option ### Microsoft Xbox Wireless Controller (4/5) — $55-70 Works flawlessly via Bluetooth or USB, available everywhere — the default if you already own one. Universally available and universally compatible. The asymmetric stick layout is what most modern games expect, and the d-pad is good enough for retro use even if it's not its strong suit. Pros: - Available at every electronics retailer - Works with every PC, Mac, phone, tablet - Robust build quality Cons: - More expensive than 8BitDo equivalents - D-pad not ideal for fighting games ### 8BitDo 8BitDo Zero 2 (4/5) — $18-25 Keychain-sized SNES-style controller — great for travel and the cheapest credible option in the lineup. Cheap and cheerful. No analog sticks and the d-pad is small enough to feel cramped for hours, but at this price it's a brilliant secondary controller for travel or a kid's first gamepad. Pros: - Cheapest credible option (~US$20) - Pocket-sized for travel - Bluetooth-only — no cable to lose Cons: - No analog sticks, no shoulder triggers - Cramped for adult hands on long sessions --- Source: [Best controllers for browser-based retro emulation](https://retrogamespace.com/guides/best-controllers-for-browser-emulation) — Mira Köhler • Last reviewed 2026-04-30 • RetroGameSpace
