This release adds cloud-sync status management, Ludusavi save detection, Archive V2, and Windows registry backups. These features, together with security, performance, and architecture changes, bring the version directly to V1.8.0.

Highlights​

Ludusavi save detection​

  • Match save locations automatically when adding games using the Ludusavi database
  • Embed a compressed manifest through rust-embed; a smaller build without the manifest is under consideration
  • Explain batch-import failures and registry paths

Ludusavi save detection

Cloud sync​

  • Add an overview of sync results, pending work, and the latest sync time
  • Track each device's position separately, supporting parallel branches and divergence on the same device
  • Run synchronization through background tasks to keep the interface responsive
  • Unify uploads and downloads through a streaming layer with hook extension points

Cloud-sync overview

Archives and backups​

  • Archive V2: replace BZip2 with Zstd and offer Store, Fast, Standard, and Maximum compression presets
  • Support files with the same name
  • Integrity checks: verify archives with XXH3 before restoring to reject corrupted backups
  • Windows registry: back up and restore registry save data with source fingerprints
  • Unchanged files: skip scheduled backups when XXH3 fingerprints show no changes

Undo and extra backups​

  • Add Undo last applied snapshot to the management page

Undo restore

  • Add management for extra overwrite backups

Interface improvements​

  • Custom fonts and appearance settings
  • Redesigned path-variable editor with clearer status information
  • Batch deletion of selected snapshots
  • Centralized feedback and notifications with shared z-index management

Interface improvements

Fixes​

  • Preserve existing files after failed cloud downloads or writes and strengthen atomic rollback
  • Fix upload protection for backends that cannot overwrite files
  • Fix ZIP timestamp compatibility
  • Prevent ZIP path traversal (Zip Slip)
  • Propagate semaphore-acquisition errors in backup_all
  • Fix unknown-backend errors when cloud sync is disabled
  • Fix the log button's position and improve log rotation
  • Remove the obsolete same-name file restriction when adding games

Performance​

  • Reduce unnecessary I/O during scheduled and batch backups
  • Reduce sidebar rendering overhead and expand it during search
  • Improve snapshot-table sorting and selection

Developer changes​

  • Add a typed lifecycle-hook pipeline for snapshot creation, deletion, and restoration
  • Refactor IPC around game-draft input and backend-assigned IDs; expose typed hook and sync commands
  • Add pre-commit checks with Husky, lint-staged, Clippy fixes, and typechecking
  • Update rgsm core to 1.8.0
  • Track multiple device positions in sync metadata
  • Upgrade archive metadata to V2, including compression presets and XXH3 hashes
  • Add save_unit_id to save configuration
  • Add Criterion benchmarks for compression algorithms

Download​

The portable build is recommended. If it will not start, install WebView2.
