Even a stable patch can cause hiccups. Here is the troubleshooting guide for NSP users:
| Issue | Solution |
| :--- | :--- |
| "Unable to start software. Return to HOME Menu." | Your signature patches are outdated. Download the latest sigpatches for Atmosphere 1.5.0+. |
| Update downloads but shows 1.0.2 instead of 1.0.3 | You have conflicting update data. Go to System Settings -> Data Management -> Delete the update only (not save data) and reinstall the 103 NSP. |
| Horseback riding still crashes | You may have a corrupted base NSP. Re-dump your base game cartridge using NXDumpTool. The 103 update only fixes the crash if the base is clean. |
| Mods stopped working | Update 103 changes the main executable (main.npdm). You need to update your mods to the 1.0.3 version. Check GameBanana for updated releases. |
