PHONE AUDIO/PERFORMANCE — 1.2.3 — November 3, 2026, America/New_York Coarse touch devices now use a fixed 12,000-cycle guest CPU budget. The tested Samsung could fall behind real time at 25,000 cycles. Desktop launch keeps the previous 25,000-cycle configuration. The original game, discs and WASM are unchanged. On supported browsers, PCM moves directly from the emulator worker to a dedicated AudioWorklet. The new processor uses fixed-rate linear resampling from the reported source rate to the hardware rate. It does not apply adaptive tempo, pitch shifting or WSOLA time stretching. A bounded180 ms prebuffer/rebuffer target absorbs delivery jitter. The previous controlled ScriptProcessor fallback remains available when the Worklet route cannot initialize. Every route retains the controlled 24x default gain,1x–40x adjustment, mute, compressor and +/-0.95 sample ceiling. The old upstream Worklet's direct destination connection is replaced; it cannot bypass the wrapper gain. The read-only CD filesystem prefetches at most two following 1 MiB blocks with at most two asynchronous requests. Demand/prefetch data share the same32 MiB LRU. All responses require206, exact Content-Range and exact byte count. Prefetch failure falls back to ordinary demand reading. CD files remain excluded from save archives; no original media bytes are changed and no full-disc download is forced. Counters stay in the local page. Scope: physical Samsung Z Fold4 Chrome 156 and desktop Edge launch/controls were tested. Phone source-clock intervals kept real-time pace after lowering the CPU budget. Some initial CD loading and scene transitions still produced missing output intervals in the instrumented tests. The tests establish an improvement, not gap-free playback for every network, scene or phone. Final perceptual smoothness confirmation and a complete phone campaign are not established. The processor/route tests run the actual JavaScript in a Node VM: a 440 Hz input remained440Hz; a 20-second stream with repeated100 ms packet holds avoided the tested underflows; gain/mute routing and cleanup were checked. These are not speaker measurements. Older digital-signal gain/RMS/ceiling measurements belong to the earlier fallback release; the shared processing chain is retained. REBUILD First build the approved1.2.2 baseline with the retained pinned runtime helper. Then run: node source/patch-mobile-runtime-1.2.3.mjs --base-vendor --output-vendor The patcher verifies all base identities and reproduces eight changed/retained runtime files. Copy the1.2.3 NOTICE, launch HTML and play/player-1.2.3.js with it. Readable additions: mobile-audio-bridge-1.2.3.js, pcm-worklet-source-1.2.3.js and read-ahead-source-1.2.3.js in this source directory. Original corresponding-source archives/licenses remain retained. Keep the original boot bundle1.2.2 and both ISO images. Save namespace remains COSOM-ManEnough-DOS-EN-v1.
