GameCube / Wii Extract & Convert Utility (v1.0)

[cyberrep]

Development & Background​

After spending many weeks experimenting with different GameCube and Wii conversion tools, I realized how fragmented the process was. Managing trimming, rebuilding, and converting between formats like ISO, GCM, WBFS, and RVZ usually required multiple separate utilities and scripts.


This project was inspired by two key sources:

• GBATemp Thread: GameCube ISO/GCM Organizer Script by syntax53
• GitHub: Dolphin Emulator RVZ/ISO Conversion Scripts by ElektroStudios

These excellent scripts gave me the idea to unify everything into a single, fully automated PowerShell utility.


I’d like to give a huge thanks to ElektroStudios and syntax53, the GBATemp community, and everyone who continues to share open tools and guides for disc preservation and conversion. Without the collective knowledge here, this project wouldn’t exist.

What It Does​

GCWII Tool.ps1 is a single, all-in-one PowerShell script that automates extraction, conversion, and organization of GameCube and Wii disc images.
It supports batch operations with detailed logging, console detection, naming consistency, and flexible overwrite policies.

Main Features​

• Unified GameCube & Wii support — one script for both systems.
• Automatic console detection (based on ID6 header).
• Smart folder and file naming, following Dolphin & WBFS conventions.
• Trim or full rebuild of GameCube discs using GCIT.
• Format conversions:
  • ISO/GCM ⇄ RVZ (via DolphinTool)
  • ISO ⇄ WBFS (via WIT)
  • RVZ → WBFS (RVZ→ISO→WBFS chain)
  • WBFS → RVZ (WBFS→ISO→RVZ chain)
• Output summary per file, showing [SOURCE], [DESTINATION], [CONSOLE], and [COMMENT].
• Overwrite modes: none, newer, or always.
• Optional deletion of source files after successful conversion.
• Support for flat or structured output folders (-nofolder mode).

Requirements​

Simply place the following executables in a Tools\ subfolder next to the script:

Game Cube Tools
DolphinTool
WIT

(Optional: 7z.exe if you plan to extend the script with archive features.)

Supported Formats​

Format	Direction	Tool Used
ISO / GCM	Trim or Rebuild	GCIT
ISO ⇄ RVZ	Convert	DolphinTool
ISO ⇄ WBFS	Convert	WIT
RVZ → WBFS	Convert (via ISO)	DolphinTool + WIT
WBFS → RVZ	Convert (via ISO)	WIT + DolphinTool

Console Detection​

• R prefix → Wii
• G prefix → GameCube
  If detection fails, Wii is assumed (can be forced with -console gc|wii).

---

Output Naming​

Mode	Example
Standard	Title [GAMEID]\Title [GAMEID].iso
Wii WBFS	Title_[GAMEID]\Title_[GAMEID].wbfs
Flat (no folder)	Title_[GAMEID].wbfs

Example Usage​

# GameCube trim rebuild
powershell -f "GCWII Tool.ps1" -scan "E:\INBOX" -dest "F:\OUT" -trim

# Convert ISO → RVZ
powershell -f "GCWII Tool.ps1" -scan "E:\INBOX" -dest "F:\OUT" -convertto rvz

# Convert WBFS → RVZ (chain)
powershell -f "GCWII Tool.ps1" -scan "E:\INBOX" -dest "F:\OUT" -convertto wbfsrvz

Output Summary Example​

[FILE 22/23]
[SOURCE] H:\gc\Zoids vs. II (Japan).iso
[DESTINATION] F:\gciso\ZOIDS VS.2 [GZSJDA]\game.iso
[CONSOLE: Game Cube]
[COMMENT: OK (TRIM)]

Closing Note​

This script is not meant to replace the great work done by others, but to simplify the process for people who want an all-in-one solution for archiving and converting their GameCube and Wii games — safely, cleanly, and consistently.


Feel free to test, improve, and share feedback!

Not to piss on your chips but is this not what NKIT UI already does?

Is there some features this tool has that tiny wii backup manager doesn't? If yes, perhaps highlight them?
