You’ve probably already discovered that while Lego City Undercover is a masterpiece of open-world comedy and family-friendly gaming, getting it to run smoothly on a Wii U emulator—or even on original hardware via a backup loader—has historically been a headache. From game-breaking bugs to performance stutters, the vanilla ROM has issues.
The issue stems from how the Wii U handles encrypted files and the specific RPX (the main executable file for Wii U games). The original scene releases failed to properly decrypt certain asset archives, leading to a pointer error. The game calls for a specific dialogue file or a city block asset, the emulator says "I don't have that," and the game freezes.
If your emulator or console throws an encryption error, the ROM is missing its ticket or title key.
Wii U ROMs usually come in three formats: WUD, WUX, or raw RPX/RPL files (Loadiine format). Converting raw encrypted data into decrypted files requires precise keys. A single mismatched key causes silent data corruption. Step-by-Step Fixes for LEGO City Undercover Method 1: Verify and Repair Files via CDecrypt Select your game folder, update folder, and DLC

Storage Requirements : The digital version of the game is approximately 19 GB to 22 GB
Wii U games require specific title keys to decrypt. Using an incorrect or slightly altered key during conversion can lead to missing textures, broken audio, or immediate boots to a black screen.
