\nRuzu int\u00e8gre notamment un kernel HLE avec ordonnanceur, fibres, IPC et services, un processeur de commandes GPU, un recompilateur de shaders et un JIT. La recompilation dynamique du code ARM est assur\u00e9e par rdynarmic, un portage Rust de Dynarmic, avec des backends natifs x86-64 et ARM64. Le projet comprend \u00e9galement rxbyak, un portage Rust de Xbyak pour la g\u00e9n\u00e9ration de code machine x86-64.
\n
\nL’\u00e9mulateur est d\u00e9j\u00e0 capable de d\u00e9marrer et d’ex\u00e9cuter des jeux commerciaux, avec l’objectif affich\u00e9 d’atteindre les performances de l’impl\u00e9mentation C++ originale. Le projet reste toutefois en d\u00e9veloppement.
\n
\nRuzu dispose \u00e9galement d’un frontend graphique ainsi que d’un frontend en ligne de commande, et peut \u00eatre compil\u00e9 sous Windows, Linux, macOS et plusieurs syst\u00e8mes BSD.

\nLes changements sont:
\n– Stability: fixed a memory\/GPU\/scheduler deadlock investigated in issue #20. Guest-memory access no longer holds an exclusive memory lock while waiting for GPU work that needs kernel scheduling to complete.
\n– Memory-copy performance: copies between processes now use an explicit page table without allocating a temporary memory object or changing the table used by the CPU. Existing GPU caches and scratch buffers are reused.
\n– Shader error handling: unsupported or invalid translator operands now produce handled shader exceptions instead of terminating the GPU thread and leaving synchronization waits blocked. Affected draws may still be skipped; this does not add support for those operands.
\n– CPU\/GPU sync: corrected tracking of images backed by non-contiguous memory to address texture corruption. Removed a whole-image download path that could overwrite reused guest memory, and restored GPU notifications for exclusive CPU writes.
\n– JIT performance: diagnostic environment settings are cached in release builds instead of being queried repeatedly while compiling CPU blocks, reducing compilation overhead. Actual improvements depend on the game and hardware.
\n– Testing and diagnostics: added regression coverage for shared memory access, process-specific page-table copies, and shader errors. Windows guest-thread diagnostics can now produce a shorter report without the full profiling history.<\/em>
