Koikatsu Partyrepack Upd Review

Navigate to your game root folder (e.g., D:\Games\Koikatsu Party). Look for a file named version.txt or repack-version.txt. Open it. It should say something like BetterRepack R8. If you don’t see it, check the launcher (InitSetting.exe) → "About" tab.

The modern version of KKManager (v1.20+) actually supports incremental updates.

Note: This works best for RX12 and newer. Older repacks still require manual UPD torrents.
