How to Install WADs on Wii 4.3u (Homebrew — Safety & Legal Warning)

Installing WADs (Wii Archive packages — channels, VC games, IOS, System Menu) on Wii 4.3U requires Homebrew Channel + a WAD manager. This modifies the console's NAND and carries risks.

Prerequisites (Follow wii.guide)

1. Wii on 4.3U → Letterbomb (SD card) → HackMii Installer → Install Homebrew Channel + BootMii (as IOS).
2. Install cIOS (d2x v10 beta52-v10.1) via d2x cIOS Installer (slots 249, 250, 251) — required for USB loading/WAD installs.
3. Optional: Priiloader (brick protection, autoboot HBC).

WAD Installation

1. Place .wad files on SD/USB: /wad/.
2. Launch YAMMM (Yet Another Multi Mod Manager) or WAD Manager 1.7 / Wii Mod Lite from HBC.
3. Select source (SD/USB) → Select WAD(s) → Install.
4. Check for "Success" / "Error -1035" (title exists) / "Error -2011" (no space).

Critical Warnings

• Brick Risk: Installing bad System Menu / IOS / Region-changed WADs = full brick (unrecoverable without BootMii/boot2 + NAND backup). Never uninstall IOS < 200 or System Menu.
• Piracy: Installing VC/WiiWare WADs you don't own is copyright infringement. Only install homebrew channels, forwarders, or your own dumped titles.
• vWii (Wii U): Different process — use wiiu.hacks.guide. Do not use Wii guides on vWii.

Safer Alternative

Use Nintendont (GameCube) / WiiFlow Lite / USB Loader GX for game backups (ISO/WBFS) — no WAD installs needed. For homebrew channels, use Homebrew Browser / Open Shop Channel to download .elf/.dol apps directly to /apps/.
