Groove Coaster not working after update + DLC : r/SwitchPirates
Here’s a concise review of Groove Coaster: Wai Wai Party!!!! on Nintendo Switch, specifically focusing on update 1 (the “fixed” version) that addressed early performance and control issues.
Before downloading any file claiming to be "groove coaster wai wai party nspupdate 1 fixed," check these three indicators:
| Feature | Broken NSP (Bad dump) | Fixed NSP (Working) |
| :--- | :--- | :--- |
| File Size | Exactly 1.52 GB | 1.53 GB (includes corrected headers) |
| CRC32 Checksum | A1B2C3D4 (Example) | FIXED2023 (Check release notes) |
| Installation Log | "Failed to import ticket" | "Ticket imported successfully" |
| In-Game Version | Shows 1.0.0 after install | Shows 1.1.0 or higher |
Pro tip: Look for release groups like "Venom" or "SUXXORS"—they explicitly tag their releases with [FIXED] inside the ZIP filename. Avoid any file that simply says Update_1.nsp without a CRC hash.
The update was natively built for Switch Firmware 10.2.0. If you were on 10.1.0 or lower, the console’s signature checks would fail silently. You would see the “Software closed because an error occurred” message. The "fixed" version patches the required system version (via sigpatches or NPFs) to allow installation on firmware 9.0.1 and above.
