Nintendo 64 emulators and tools can disagree on raw save-memory byte ordering and packaging. Phase 35 keeps the verified operation intentionally small: exact-size raw EEPROM/SRAM/FlashRAM input plus a user-selected reversible byte permutation. It does not attempt to identify the game or silently choose a target convention, and it leaves emulator-specific composite containers for the dedicated ecosystem phase.
Emulator & Retro Tools
N64 Save Converter
Validate exact raw Nintendo 64 EEPROM, SRAM, or FlashRAM geometry and apply an explicit reversible byte-order transform without guessing the target emulator.
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
.eep.sra.fla
Platforms
Nintendo 64
Supported versions / editions
Raw N64 EEPROM, SRAM, and FlashRAM byte arrays of the explicit supported sizes. Controller Pak files, combined/composite emulator save files, compressed containers, and emulator save states are separate formats.
Input constraints
Input must exactly match the user-selected raw memory type: 512-byte EEPROM, 2048-byte EEPROM, 32 KiB SRAM, or 128 KiB FlashRAM. Supported transforms are identity, byte swap within every 16-bit pair, or byte reversal within every 32-bit word; all preserve file length.
Known limitations
The tool does not infer byte order from content, promise compatibility with a named emulator, alter game-specific checksums, merge save-memory regions, convert Controller Pak data, or rewrite RetroArch/Mupen64Plus composite containers. The user must know the source/target byte-order convention.
Output / result
A new raw save with the same exact byte length and the explicitly selected byte permutation. Identity mode provides a validated copy.
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
Choose the known N64 save-memory type, select the byte-order transform required by your documented workflow, transform locally, and test the downloaded copy. Applying the same swap transform twice restores the original bytes.
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.

Tool-specific privacy notes
Phase 36 reads a selected file only after explicit local file selection. Parsing, inspection, normalization, extraction, and supported conversions run in the browser. The emulator-retro runtime contains no fetch, XMLHttpRequest, WebSocket, or sendBeacon calls. The shared file ceiling is 16 MiB, with stricter format-specific limits where appropriate.
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
Wrong-size input is rejected instead of padded or truncated. If an emulator uses a larger composite .srm container, do not extract or overwrite regions by guesswork; use a format-specific converter when verified support becomes available.
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 against Mupen64Plus raw save-memory geometry references and deterministic fixtures for exact size validation, 16-bit swaps, 32-bit reversals, identity copies, length preservation, transform involution, and unsupported-size rejection.
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 N64 Save Converter 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.
