beetle_libretro.cpp targets the C++ beetle-psx tree; upstream master has been converted to plain C and no longer compiles against it. Documented the working recipe: pin beetle-psx at 5759277b (the wtrace patch's base, located via the patch's own blob hash), apply beetle_wtrace_hook.patch, and apply the new beetle_sio_trace_hook.patch — FrontIO::SetSIOTraceCallback (fires once per completed SIO byte exchange), a hook beetle_libretro.cpp required that was missing from the committed patch set. Verified on Linux/Xvfb: psx-beetle boots Kula World to demo gameplay and serves ping/screenshot over the shared TCP debug protocol, alongside kula-runtime — the two-process oracle setup from CLAUDE.md §16 now works in this environment. Runtime-created per-game .mcr files are gitignored. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BdjxoRB1f9VQsNzZayCgGS
