| Problem | Solution | |--------|----------| | Black screen on launch | Enable “Game Patching” in Luma3DS config (boot with Select). Ensure your CIA is region-free (most updated versions are). | | Bottom screen flicker | Toggle 3D slider off. Some widescreen patches conflict with 3D rendering. | | Save file corrupted | Use Checkpoint homebrew to import a clean save. Do not use DS save files directly. | | Slowdown during final boss | If on Old 3DS, switch to New 3DS. The final fight with Elder Princess Shroob renders 16 sprites at once. |
