PlayStation

Rust already has real, working homebrew toolchains for Sony's PlayStation-family handhelds (rust-psp for PSP, community vitasdk bindings for PS Vita), which proves Rust code can run on this hardware family at all. Since Servo (the engine underneath Roves) is written in Rust top to bottom, that same portability carries over: a port is mostly about implementing Roves' native integration layer — window/surface creation, controller input, GPU setup — against the target console's own APIs, not about rewriting the rendering engine itself. Modern PlayStation hardware (PS4/PS5) additionally needs Sony's own licensed developer SDK, which isn't publicly downloadable the way the homebrew toolchains above are — a registered developer account is the actual gate there, not Rust support.
