PUAE CD browser player / GPL-2.0-or-later
Upstream: https://github.com/libretro/libretro-uae
Revision: 7387937066b1b693816c3b4e2b7a0c601d41363d
Toolchain: Emscripten 4.0.20 (emsdk), Linux.
Firmware and game discs are external; neither is included in these sources.

Extract corresponding-source.tar.gz. In its integration/ directory, run:
  bash build.sh
The script compiles the modified PUAE source into a static archive, then
links the bridge into core.js/core.wasm. Copy worker.js and audio.js alongside
them. frontend.js is the ES module used by the site player.

The emulation thread executes load/run/serialize/reset/flush/close commands;
the JavaScript runtime thread stays available to service filesystem proxies.
Do not move libretro execution onto the runtime owner: CD-audio threads can
otherwise deadlock while requesting proxied filesystem operations.

Requires cross-origin isolation and SharedArrayBuffer. Game discs are read
only, through same-origin HTTP byte ranges; archive media lives in browser
memory. NVRAM and checkpoints are stored locally in the visitor browser.

Source changes include typed C/C++ callback signatures, a typed UAE thread
trampoline, Emscripten thread sleep, and the libretro-common static build.
The site's existing Amiga player is separate and is not upgraded by this core.

Archive decoders: unchanged pinned EmulatorJS 4.2.3 extractzip.js/extract7z.js.
They live beside this core so their Worker scripts carry the isolation headers;
other players keep their existing decoder URLs and headers.
