Instaurix v0.1.1-alpha

Instaurix v0.1.1-alpha

This experimental update introduces the Instaurix name and advances the reference runtime, memory handling, software display and GPU copy interpreter.

Changes

• Extended HLE services allow reference applications to complete default libnx initialization, reach main and clean up.
• Software framebuffer presentation supports one, two and three buffers.
• Added modular GPU profiles and a bounded historical Maxwell copy interpreter supporting linear copies, pitched 2D copies and restricted block-linear source conversion.
• Guest reference programs generate their own copy commands and verify output bytes, padding, guards and hashes.
• Sparse memory tracking reduces the measured legacy test's peak memory usage to approximately 104 MiB.
• Added automatic Windows test diagnostics and expanded English documentation.

Validation

• 127/127 CTest suites passed locally in Windows Debug and Release.
• The update passed all four GitHub CI configurations: Ubuntu and Windows, Debug and Release.
• Reference binaries and the existing CPU LFS datasets retain their recorded hashes.

Current limitations

No commercial games or native Switch 2 compatibility have been validated.

The ARM64 CPU remains incomplete. GPU copying currently uses a CPU-side historical HLE interpreter; it does not demonstrate general GPU rendering, shader execution or native hardware synchronization. Audio and commercial-game loading remain unvalidated.

Switch2Emu v0.1.0-alpha

Présentation

Première préversion publique de Switch2Emu, un projet expérimental d'émulation en C++20 visant à terme l'exécution de jeux Nintendo Switch 2 sur PC.

Le développement se concentre sur les fondations de l'émulation ARM64, le chargement des programmes et la mise en place progressive des services système.

Fonctionnalités présentes

• Interpréteur ARM64 avec prise en charge partielle des instructions.
• Mémoire paginée et bus mémoire avec périphériques de test.
• Chargement de programmes binaires ARM64 et ELF.
• Développement d'un environnement HLE de référence.
• Tests automatisés et programmes de référence reproductibles.
• Démonstration interactive disponible dans le dépôt.

Limitations

• Aucun jeu commercial n'est actuellement validé comme compatible.
• La compatibilité native Nintendo Switch 2 n'est pas démontrée.
• Le CPU et les services système restent incomplets.
• Le GPU, l'audio, les entrées natives et de nombreuses fonctionnalités matérielles restent à développer.

Compilation et tests

Les instructions de compilation et de test sont disponibles dans le README.

Cette version est une préversion expérimentale destinée principalement aux développeurs et aux personnes intéressées par l'émulation.

Switch2Emu v0.1.0-alpha

Overview

First public pre-release of Switch2Emu, an experimental C++20 emulation project aiming to eventually run Nintendo Switch 2 games on PC.

Development focuses on the foundations of ARM64 emulation, program loading, and the progressive implementation of system services.

Current Features

• ARM64 interpreter with partial instruction support.
• Paged memory and a memory bus with test peripherals.
• Loading of ARM64 binary programs and ELF files.
• Development of a reference HLE environment.
• Automated tests and reproducible reference programs.
• Interactive demo available in the repository.

Limitations

• No commercial games have been validated as compatible.
• Native Nintendo Switch 2 compatibility has not been demonstrated.
• The CPU and system services remain incomplete.
• The GPU, audio, native input support, and many hardware features remain to be implemented.

Build and Testing

Build and testing instructions are available in the README.

This release is an experimental pre-release intended primarily for developers and people interested in emulation.
