Prelude 4.0.10
Changes
- Safer automatic updates: validate the downloaded NRO before replacing the installed version, preserve a recovery backup, and attempt rollback if installation fails.
- Detect SD read, write and file-close failures instead of reporting a successful update.
- Select the correct
nextendo.nrorelease asset; retry transient download errors and tolerate longer CDN stalls. - Exit Prelude after a successful update so old code cannot continue using the new version's embedded resources.
- Add early startup traces and visible resource/interface initialization errors instead of silently returning to the launcher.
- Improve resource-copy failure handling when applying Nextendo mode.
Game patches and host resources from 4.0.9 are retained, including Game Boy Advance 3.4.0.
Installation
Close Prelude and replace the NRO you actually launch, keeping its filename and location. Older installed versions still run their old updater; if their download fails, replace the NRO manually once to adopt this correction.
Validation and diagnostics
The full Switch build, updater failure-injection tests and hosts-refresh tests passed. The exact startup/network failure reported on the affected Switch still needs hardware confirmation. If it persists, retain sd:/prelude_trace.txt before relaunching Prelude and include it in the report.
The updater retains a sibling .prelude-backup recovery copy. If an interrupted installation leaves the main NRO absent, retain that backup and restore it to the original filename.
