Release v1.0.0

Dolphin for Switch 2 (kaiHEN) — first test release

An unofficial Switch 2 port of dolphin-nx (Dolphin 1.2.2 for Switch by NaGaa95), built with ounce-devkit for kaiHEN. It's an early test build: expect bugs, and please report them here, not to the Dolphin or dolphin-nx projects.

Requirements

• A Switch 2 running kaiHEN
• Copy dolphin.nro to sdmc:/switch/ and start it from hbmenu

What's new

• Runs on Switch 2. It's built against libounce and OunceVK, so it renders with Vulkan through NVK.
• Dolphin's JIT works under kaiHEN. Generated code is published to kaiHEN's RO service, which runs it.
• Exiting no longer breaks hbmenu. Before, closing Dolphin left hbmenu on a black screen until kaiHEN was injected again. Dolphin's USB drive support was the cause, so it's turned off on Switch 2 for now. You can now go back to hbmenu with Dolphin's Exit option, from the launcher or after playing a game.
• Cleaner exit. Leftover threads and their stacks are released before hbmenu loads.
• Diagnostics. Logs are written to sdmc:/switch/dolphin/diag/: boot.log, stderr.log, and crash.log after a crash. Please attach them to bug reports.

Known issues and limitations

• USB drives are not supported on Switch 2 for now. Games on the SD card and SMB network shares still work.
• Closing with HOME → Close hasn't been tested with this build yet.
• NVK is not a conformant Vulkan driver, so some games may have graphics problems.
• Performance isn't tuned yet. Each block of JIT code costs a round trip to kaiHEN, and batching those is planned.

Credits

This port builds on the work of the Dolphin Emulator Project, NaGaa95 (dolphin-nx), the kaiHEN contributors and ouncebrew (kaiHEN, libounce, OunceVK, ounce-devkit), switchbrew, devkitPro and Mesa. It also uses DarkMatterCore's libusbhsfs and Ronnie Sahlberg's libsmb2. Kaizhar by wowilookgood is the source of the approach to exiting cleanly. The full list is in Switch2/README.md.

Licensed under GPLv2+, like Dolphin and dolphin-nx.
