This is not a corruption repair. The source card must already pass the strict GameCube filesystem parser and all four directory/BAT metadata blocks must validate. SaveEditor applies the documented signed update-counter selection rule to the two valid directory copies, copies the selected active directory only into the inactive directory block, increments the rebuilt copy update counter, fixes that block checksum, and emits a new card only after strict reopen proves the filesystem remains valid.
Emulator & Retro Tools
GameCube Directory Redundancy Rebuild
Refresh the inactive valid GameCube directory mirror from the parser-selected active directory copy, incrementing only the rebuilt copy counter and checksum before strict reopen.
01 / Tool workbench
Use the runtime only when it is actually ready.
The application shell fails closed. An input interface is not enabled merely because a WordPress Tool record exists; the declared engine must be registered in the current build.
Session change summary
No output has been built in this session.
02 / Compatibility
Know the supported input before opening a file.
Compatibility fields are intentionally explicit. Missing values stay unclaimed rather than being filled with generic assumptions.
Accepted extensions
.raw.gcp.bin.mem.mcd
Platforms
GameCube
Supported versions / editions
Raw/Dolphin-compatible GameCube memory-card images already accepted by the strict Phase 46 parser.
Input constraints
Exact supported raw GameCube memory-card geometry; valid header; all directory/BAT metadata checks valid; complete strict filesystem parse succeeds; active/inactive directory blocks differ; active signed update counter must not be 32767; only the inactive 8 KiB directory block may change.
Known limitations
No invalid-card repair, no header repair, no BAT rewrite, no directory synthesis, no payload edit, no counter rollover guess, no selection when the strict source parser fails, and no changes outside the inactive directory block.
Output / result
A new full-card copy with only the inactive directory block rebuilt from the validated active directory, assigned the next safe update counter and matching checksum pair.
03 / Instructions
Use a reversible workflow.
File-oriented workflows start with an untouched original. Tool-specific instructions add only details documented for this utility.
- 01Keep the original
Preserve an untouched copy before creating or transforming binary output.
- 02Confirm scope
Match the file size, format, platform, and version to the support information on this page.
- 03Process locally
Use the runtime only when the page reports that its declared engine is loaded.
- 04Validate output
Compare or test the result before replacing any working source file.
Tool-specific steps
Use only on a card that already validates but has divergent directory mirrors. Preserve the original. Download the rebuilt copy only after SaveEditor confirms strict source parse, exact active-copy selection, bounded target write, and strict reopen.
04 / Privacy and processing
The processing mode is part of the product contract.
SaveEditor.com should state local processing only when the implementation truly keeps file contents in the browser. Server or hybrid processing must be disclosed just as clearly.
Declared mode
Browser local
Runtime state
Operational
Tool-specific privacy notes
Phase 52 reads only the explicitly selected local file in the browser. The nintendo-recovery-v1 runtime contains no fetch, XMLHttpRequest, WebSocket, sendBeacon, form upload, server-side save processing, or telemetry path. The permanent 16 MiB per-file ceiling remains in force and the selected source is never modified.
05 / Troubleshooting
When a file is rejected, do not force it.
A rejection can indicate an unsupported size, format, version, platform, or byte sequence. Preserve the original and correct the input instead of bypassing validation.
Re-check the documented input type and browser size limit before retrying.
A generic converter does not imply support for every game-specific container, signing scheme, or serialization format.
Return to the untouched source instead of repeatedly processing a damaged or partially transformed file.
Known Tool issues
If the card is corrupted, use the narrower Phase 47 recovery profile. If both directory copies are already identical or the active counter is at signed rollover, no Phase 52 output is generated.
06 / Verification
Support claims should be traceable.
The verification date, method notes, and public references are kept separate from marketing language so compatibility can be reviewed over time.

Method notes
Verified with clean divergent valid GameCube directory fixtures, signed counter/tie selection, identical-copy refusal, signed rollover refusal, strict source/reopen checks, byte-scope assertions, checksum reconstruction, independent Python reproduction, and full regression/source-package parity.

07 / FAQ
Questions to answer before editing.
These answers are generated from the Tool record and current runtime state rather than generic compatibility promises.
Is GameCube Directory Redundancy Rebuild ready to use?
The Tool record is verified and declares an operational runtime. The page enables its input controls only when the declared engine module is loaded in the current build.
Does processing stay in the browser?
Yes for this declared mode. The loaded runtime processes the explicit input in the browser; Tool-specific privacy notes describe the exact scope and limits.
Should I keep the original file?
Yes. Keep an untouched source file until any generated output has been validated.
What if my input is rejected?
Use the validation message to correct the base, encoding, width, timezone, byte alignment, or size. The runtime does not guess through invalid input.
