| Format | Primary Use & Compatibility | File Size & Compression | | :--- | :--- | :--- | | | Universal use, full 1:1 disc copy. Works with everything: emulators, USB loaders, and burning software. | Original, huge size (~4.7GB). No compression. | | WBFS (.wbfs) | The standard for real Wii hardware . Highly compatible with USB loaders on the original console. Also works with most emulators. | Moderate reduction (scrubbed/partitioned). Saves significant space vs. ISO, but not as small as newer formats. | | GCZ (.gcz) | Dolphin Emulator's older format . Great for PC-based emulation on older Dolphin versions. Not ideal for real Wii hardware. | High compression, lossless . Can drastically reduce file sizes. | | NKIT (.nkit.iso) | Specialized high compression . Offers one of the smallest file sizes, but can have compatibility issues with some emulators or loaders. | Maximum compression, non-lossy (data is recoverable to 1:1 ISO). To achieve the smallest size, this is a top contender. | | RVZ (.rvz) | Dolphin's modern, recommended format . Supported by newer Dolphin builds. Offers excellent compression and features, making it the current standard for PC emulation. | Highly efficient, lossless . Often matches or beats the compression of NKIT and WBFS. | | WIA (.wia) | Niche but efficient archive format. Supported by WIT tools and newer emulators like Dolphin. | Lossless . A predecessor/inspiration for RVZ, similar performance. | | CISO (.ciso) | Archived/Outdated . A legacy compressed format not recommended for modern use. | Lossy (discards unused data permanently). | | Archives (.7z/.rar/.zip) | Backup/Storage Only . Standard archives cannot be used for playing games. They must be extracted back to a playable format like ISO or WBFS first. | Excellent for storage , but requires extraction before use. |
