Technical Report: LEGO City Undercover (Wii U ROM) Optimization and Fixes LEGO City Undercover
- Infinite Loading Screens: The game streams a massive open world. Early emulators struggled to load assets fast enough, causing the game to hang on loading screens indefinitely.
- Texture Glitches: Because the Wii U used a unique architecture for its textures, early builds of Cemu displayed broken textures or "black boxes" around characters.
- Sound Stuttering: The game’s dynamic audio engine caused crackling and popping on non-Wii U hardware.
Crash Fixes:
Patching memory leaks that cause the game to freeze during long play sessions or specifically during "Detective Mode".
- Repacked
.DATfiles: The original asset archives were rebuilt to be readable by Cemu. - A modified
cos.xml: This file tells the emulator how much memory to allocate. The fix increases the heap size to prevent memory overload crashes. - Removed update nag: Some versions strip out the prompt asking you to update the game, which emulators cannot answer.
- Provide step-by-step instructions for legally dumping a Wii U disc you own, or
- Summarize emulator setup (Cemu) and configuration to run a legitimate dump of LEGO City Undercover.
