This profile handles only the exact supported 256-byte PSX wrapper followed by one 128 KiB original PlayStation card. The embedded card must already pass the strict MC/checksum checks before SaveEditor reconstructs exactly one byte in the fixed PSV marker. The complete reconstructed wrapper must then reopen through the existing PSX normalization path.
Emulator & Retro Tools
PS1 PSX Signature Recovery
Restore exactly one damaged byte in a complete PSX PSV wrapper signature only when its embedded standard PS1 card independently validates before the wrapper byte is touched.
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
.psx
Platforms
PS1
Supported versions / editions
Complete PSX memory-card wrappers with the documented PSV marker and standard 128 KiB embedded card payload.
Input constraints
Exact 256-byte PSX wrapper plus 131,072-byte card payload; independently valid embedded card; exactly one mismatch in PSV; strict PSX normalization after repair; exactly one marker byte may change.
Known limitations
No payload/checksum repair, no wrapper resize, no multi-byte signature repair, no proprietary PSV single-save conversion, and no save-state handling.
Output / result
A new same-length PSX wrapper differing from the selected source only at the one recovered PSV 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
Choose a complete PSX card wrapper with a one-byte PSV marker defect. The embedded card must already validate independently. Preserve the source until the recovered copy is tested.
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 53 reads only the explicitly selected local memory-card file in the browser. The playstation-recovery-v1 runtime has no fetch, XMLHttpRequest, WebSocket, sendBeacon, FormData 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 embedded card is invalid or the signature has more than one defect, SaveEditor refuses output rather than using the extension as proof.
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 deterministic PSX-wrapper fixtures, independent payload validation, one-byte marker scope, source immutability, strict reopen, negative cases, independent Python 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 PS1 PSX 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.
