This recovery changes only one byte of the documented Datel MaxDrive/Pro SAV marker. Exact SAV wrapper geometry is required before recovery. SaveEditor restores one and only one mismatch against DATELGC_SAVE, then the complete reconstructed file must pass the existing strict SAV parser including directory-entry block-count and payload-size checks.
Emulator & Retro Tools
GameCube Datel SAV Signature Recovery
Restore exactly one damaged byte in DATELGC_SAVE only when exact Datel SAV geometry and the existing strict parser validate the entire reconstructed single-save wrapper.
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
.sav
Platforms
GameCube
Supported versions / editions
Dolphin-compatible Datel MaxDrive/Pro GameCube SAV single-save containers.
Input constraints
Exact 0xC0 Datel SAV wrapper remainder, at least one complete 8 KiB save block, and exactly one mismatching byte in DATELGC_SAVE. Existing strict SAV parsing must accept the reconstructed copy.
Known limitations
No multi-byte marker repair, no byte-swap inference beyond the existing parser, no directory-entry or block-count repair, no payload edit, and no mutation outside the one signature byte.
Output / result
A new Datel SAV copy differing from the source at exactly one documented signature byte.
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
Select a damaged Datel SAV. Continue only if SaveEditor reports one signature-byte mismatch, exact wrapper geometry, and a successful strict parser reopen after reconstruction.
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.

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
Generic .sav files are not enough. Geometry, marker, embedded directory entry, block count, and final size must all agree after the one-byte reconstruction or output is refused.
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 strict Datel SAV fixtures, each one-byte marker corruption, zero/multi-byte refusal, size/block-count failure cases, one-byte scope, strict reopen, independent reconstruction, 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 Datel SAV Signature Recovery 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.
