Installing WADs can be risky; if a file is corrupt or incompatible, it can "brick" your console. Always follow these safety steps: Complete Softmod Guide - CustomizeMii - Google

If you own the original retail disc (NTSC-U, PAL, or NTSC-J), here is the to create your own WAD file:

| Issue | Cause | Solution | |-------|-------|----------| | Dolphin says “WAD installation failed: Invalid signature” | Clean WAD missing decryption key | Place your Wii’s keys.bin in Dolphin’s user folder. Or use a patcher to “trucha sign” the WAD. | | WAD installs on Wii but black screens on launch | Region mismatch (e.g., PAL WAD on NTSC Wii) | Use or WiiBaFu to change the region flag, or install Priiloader with region-free hacks. | | Newer SMBW patcher says “Bad WAD size” | You tried using an ISO or RVZ file instead of a true WAD | Convert your ISO to WAD using WiiBackupManager + ShowMiiWads or dump again correctly. | | “ticket not found” error in YAWMM | WAD file is incomplete or corrupted | Redump from your original disc. Never download WADs from untrusted file hosts. |
