The run of work that took the translated build from "boots" to "playable". Engine: - Flat guest mapping replaces the software MMU on aarch64 hosts. A 4 GiB PROT_NONE reservation lets a 32-bit guest address zero-extend safely, so tcg_out_qemu_ld/st short-circuit before tcg_out_tlb_read and the prologue materialises the base into X28. Measured 1.24x (51 vs 41 fps, interleaved A/B). Note the base must be set BEFORE UC_INIT - Unicorn inits lazily, and setting it after uc_open silently falls back to softmmu. - num_get<char> facet implemented, which was the real cause of the crash after the prologue race; a full race is now playable end to end. - Thread-stack free list + ReleaseThreadEngine, fixing the arena leak that showed up as a black screen when entering a race. kMaxGuestThreads 16 -> 64. - Real ARM32 FMOD now runs in-engine via the Java FMODAudioDevice bridge, with a per-thread JNIEnv. Two of the three blockers were our own single-image-era guards. Host/app: - Native crash handler: async-signal-safe, decodes the host fault back to a guest address, writes a report file and nothing else. CrashReportActivity picks it up on the NEXT launch, zips it, and offers to share. No backend, no automatic upload. - Game data ships inside the APK and self-extracts on first launch, so a tester installs one file and plays. Copy-to-.part-then-rename, with a free-space check up front. - EGL context preserved across pause, fixing black textures on resume. - Navigation bar hidden and re-hidden on focus gain; volume keys reported as system keys, checked before the loading-state gate. - x86_64 added to abiFilters: the ARM32 guest runs under tcg/i386 with no houdini in the path. The flat mapping is aarch64-only, so that host falls back to the software MMU - commented at the abiFilters line. Ignore rules added for app/translated/ (611 MB of signed release APK, which also carries the bundled OBB) and ostream_repro/build/. Co-Authored-By: Claude <noreply@anthropic.com>
