I reverse engineered a board game

A developer reverse engineered the "Hitster" board game's Android app and discovered the developers had encrypted song data using basic Base64 encoding and AES encryption with the decryption logic openly visible in the decompiled code. By extracting and decrypting the `gameset_database_4.json` file, they were able to map card IDs to Spotify tracks, exposing how the game associates regional card versions with specific songs despite the app's requirement for a music streaming subscription.
