ProsperoWeb 0.1.0

First release. A WebKit web browser for the jailbroken PlayStation 5, driven by
the controller and verified on the developer's console (firmware 13.42).

Added

• Native home-screen title PRWB00001, launched like any other app and placed on the console's Media row. The browsing profile is created in /data/prosperoweb/. The websrv tile is kept as a fallback launch path.
• Browsing: tabs, an address bar with URL and search normalisation, back, forward and reload, bookmarks, history and session restore.
• Input: a DualSense pointer on the left stick or the touchpad (slide, tap, two-finger scroll, press-and-slide to drag), tab switching and a menu; a USB keyboard; text entry through the console's own keyboard dialog with a built-in on-screen keyboard as the fallback.
• Media: HTML5 video and audio through an ffmpeg engine, with Media Source Extensions (YouTube-style players), progressive MP4 and WebM, and native HLS. Hardware decoding of 8-bit H.264 and HEVC through the console's sceVideodec2, with automatic fallback to software. Video is composed under the page; audio is mixed and played by the UI process.
• Fullscreen: the HTML5 Fullscreen API and a chrome-hiding fullscreen mode.
• JavaScript JIT (baseline and DFG) and WebAssembly, both switchable off.
• Bundled fonts covering Latin, Cyrillic, CJK and colour emoji.
• English and Russian interface.

Known limitations

• A privileged ELF loader (elfldr on 127.0.0.1:9021, started by etaHEN) is required: the sandboxed title cannot create its own processes.
• No DRM sites: there is no content decryption module, by design.
• No GPU acceleration: software rendering only.
• No WebAudio.
• Only firmware 13.42 is tested; other versions are untested.
