jpcheat Posted 6 hours ago Posted 6 hours ago LaunchBox Database Matcher 2 View File 🕹️ Database Matcher & Auditor 2.0 for LaunchBox Database Matcher & Auditor 2. is an automated library auditing and database matching plugin for LaunchBox. It scans your game library for unmatched titles (games missing a LaunchBox Database ID) and uses a multi-threaded fuzzy matching engine to accurately find and assign their official LaunchBox DB IDs. Based on slipsystem's Launchbox Games Database Matcher idea but taken it a bit further. Once DB IDs are assigned, you can instantly scrape missing box art, clear logos, fan art, and trailers using LaunchBox's native metadata download tools. ✨ Key Features 📊 Full Library Auditor: Instantly scans your library or specific platforms to identify unmatched games, missing box art, missing logos, and missing video snaps. ⚡ Fast Indexing & Multi-Threading: Uses an in-memory inverted word index to search the launchbox database records. 🧠 Smart Title Normalization: Strips bracket tags (USA), disc tags (Disc 1), version strings (v1.02), and punctuation. Automatically splits CamelCase & PascalCase titles without spaces (e.g., converts SuperMarioBros →→ Super Mario Bros). 🎯 Fuzzy Matching Engine: Consecutive Word Sequence Scoring: Prioritizes titles with 2 or more exact sequential matching words (e.g., matches "The Empire Strikes Back" to "Star Wars Episode IV: The Empire Strikes Back"). Sub-phrase & Sliding Window Detection: Handles titles embedded within series prefixes or subtitles. Phonetic Penalty: Heavily penalizes false phonetic matches that lack actual word overlap. 🌐 Optional Cross-Platform Matching: Toggle cross-platform searching to find matches across alternate console/arcade releases . Only use this if your not fussed about accuracy. This gives many more results and more accurate title hit rate at the cost of having other platforms art work. I figured any artwork for the game is better than none. this is off by default though. 🔍 Interactive Match Resolution: You can edit cleaned titles directly in the grid and click 🔍 Search to re-query instantly for that title. Double-click any game row to view up to 20 top candidate matches (top 10 current platform + top 10 cross-platform matches if enabled). Assign confidence threshold slider (default: 80%) for safe bulk auto-matching. High the slider the less results but more accurate. Installation : Extract the LaunchBox.DatabaseMatcher folder to the launchbox\plugin\ folder and Restart Launchbox Currently WIndows only as far as i know. 🎯 Primary Use Cases Fixing Unmatched Imported ROM Sets: Quickly assign DB IDs to imported MAME, homebrew, custom ROMs, or Japanese/European collections. Much higher accuracy/ hitrate on malformed file titles. Metadata & Media Scraping: Fixes many more grey placeholder boxes than the standard launchbox search, by preparing unmatched games for LaunchBox's built-in media downloader and looser word scoring engine. Cross-Platform Media Fallbacks: Match obscure ports or arcade titles to console database entries when a specific platform entry is missing media. 💡 Tips for Best Results Step-by-Step Workflow: Select a platform (or All Platforms) and click 1. Audit Library. Choose whether to turn on search all platforms for other game ports/versions. Warning this will give potentially inaccurate artwork, purists stay away! if in doubt leave it off. Click Search DB Matches to run fuzzy matching. Adjust the Assign Threshold Slider (80% is recommended for safe bulk auto-assignment). Click 3. Auto-Assign Matches. Click 4. Save to LaunchBox to commit changes permanently. Scan for Media/Artwork in the normal way Manual Override: If a game doesn't match correctly automatically, before "Auto assign matches" edit the text in the Clean Title (Editable) column and click 🔍 Search next to that row. Inspect Candidates: Double-click any row to open the candidate selection dialog and manually pick the exact DB entry you want. Non platform results will be at the bottom if enabled Download Media: After saving your matches, go to LaunchBox's top menu: Tools →→ Download →→ Update Metadata and Media for Selected Games to fetch missing artwork! If your collection is large i would suggest doing one platform at a time as searching can take a while. Submitter jpcheat Submitted 07/30/2026 Category Third-party Apps and Plugins Quote
