Adding Custom Songs to Guitar Hero World Tour (Wii)

You cannot add custom songs to Guitar Hero World Tour on Wii. The game uses a proprietary, encrypted song format (.chart / .mid + audio stems) and has no official or community-supported custom song pipeline on the console.

Why It's Blocked

• Songs are authored in a closed format (GHWT's "Music Studio" creates simplified versions, not full charts).
• Wii's security (signatures, encryption) prevents unsigned content loading.
• Licensing: Activision/Neversoft locked down DLC to control distribution and royalties.

Alternatives for More Music

• DLC (Discontinued): ~500 songs were sold as DLC packs. No longer purchasable (Wii Shop closed 2019). If you bought them previously, they may still be redownloadable from your Download History.
• PC Version + Mods: Guitar Hero III: Legends of Rock PC has a thriving custom song scene (Clone Hero is the modern standard—free, supports GHWT charts, keyboard/controller/guitar). Highly recommended.
• Clone Hero (PC/Mac/Linux): Free, open-source, loads custom charts (.chart, .mid, .gh), supports GHWT 5-lane + drums + vocals. Active community, thousands of songs.

Bottom line: On Wii, you're stuck with the on-disc setlist + any previously purchased DLC. For custom songs, play Clone Hero on PC—it's the spiritual successor the community built.
