A native port built on the Petari decompilation (previous commit): an HLE platform layer (OS, DVD, GX, audio, input, NAND) under the game's own code, an OpenXR presentation (a diorama around the player, a giant screen, the HUD and settings as compositor layers, SpaceWarp, dynamic resolution), Touch Plus controls, the tools that convert your own game files (tools/cook, which also takes the few pieces of data the game's executable holds from your sys/main.dol), and the port's changes to the decompilation (`git diff petari-base -- decomp`). README.md explains installing and building, docs/TECHNICAL.md how it works. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
