Thanks for providing this guide! This put me on the right track and badges are now displaying. As noted in the guide, all my Wii games are missing a hash:
<RetroAchievementsHash>COULDNTFILEHASH</RetroAchievementsHash>
I closed Launchbox, removed all of these references from the Nintendo Wii.xml file. Saved. Relaunched Launchbox. Ran "Scan" from Tools -> Options -> Integrations -> RetroAchievements
All games are still coming back with "COUNLDNTFILEHASH". My Platform "Scrape As" is set to "Nintendo Wii". I assume that's ok, as it matches the formatting of other Nintendo platforms that are correctly hashing.
I then download RAHasher 1.8.3 from RetroAchievements Github. I scanned one of my Wii games using that RAHasher. It returned the correct hash. I then scanned the game with the RAHasher.exe from LaunchBox\ThirdParty\RetroAchievements. I got this error:
"Unsupported console for file hash: 19"
I replaced the RAHasher.exe in LaunchBox\ThirdParty\RetroAchievements with the 1.8.3 version I downloaded. Closed Launchbox. Removed all bad hashes from the Nintendo Wii.xml file again. Relaunched LaunchBox. Re-scanned, and I've got achievement badges!
Thank you so much for the guide. I wouldn't have been able to figure this out without knowing about the XML file where the hashes are stored.
