Sega Dreamcast Controller

Dreamcast games run through RetroArch's Flycast core — and The Vault maps your pad to the Dreamcast controller for you, with in-game save/load hotkeys, at every launch.

Button map

Face buttons show the cross-console mapping — PlayStation / Xbox — since The Vault works with all three controller styles. The Dreamcast's L and R are analog triggers, so they map to your pad's L2 / R2. There's no Select on a Dreamcast pad — in-game hotkeys use your controller's own modifier (Create on a DualSense).

How it works

The Dreamcast controller has a single analog stick, a D-Pad, four face buttons (A/B/X/Y), two analog triggers (L/R) and Start — no Select. The Vault maps your controller to that layout: sticks and D-Pad pass straight through, the analog triggers become your pad's L2/R2, and the face buttons follow the cross-console positions shown above.

Save & load hotkeys

Because the Dreamcast pad has no Select button, in-game hotkeys use your controller's modifier — Create on a DualSense — exactly like the other RetroArch systems:

Combo	Action
Create + R	💾 Save State
Create + L	📤 Load State
Create + Start	Quit to library
Create + ▲ / ▼	Next / previous slot
