The VGS/MEM wrapper is eligible only at the exact supported 64-byte-header plus 128 KiB-card size. SaveEditor first validates the embedded card independently, including its MC identifier, header checksum and all directory-frame checksums. It then reconstructs exactly one damaged byte in the fixed VgsM marker and requires the existing VGS normalizer to reopen the result.

PS1 VGS Signature Recovery
Restore exactly one damaged byte in a complete VGS/MEM VgsM wrapper signature only when the embedded 128 KiB PS1 card independently validates before wrapper reconstruction.
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
.vgs.mem
Platforms
PS1
Supported versions / editions
Complete VGS/MEM card wrappers using the VgsM signature and standard embedded 128 KiB PlayStation card.
Input constraints
Exact 64-byte VGS wrapper plus 131,072-byte card payload; embedded raw card independently valid before repair; exactly one VgsM mismatch; strict VGS normalization after repair; only that marker byte may change.
Known limitations
No payload repair, no wrapper resizing/padding, no GME header synthesis, no checksum changes, no multi-byte signature reconstruction, and no save-state conversion.
Output / result
A new same-length VGS wrapper differing from the source only at the one reconstructed VgsM 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 VGS/MEM card image with a one-byte signature defect and intact embedded card. Keep the source; download only after independent payload validation and strict wrapper reopen pass.
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
Wrong geometry, an invalid embedded card, zero or multiple marker defects, or failed strict reopen produces no output.
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 exact-size VGS fixtures, independently valid embedded cards, one-byte marker reconstruction, payload byte-equality checks, source immutability, strict normalization, 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 VGS 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.
