This read-only Tool recognizes the fixed DexDrive GME wrapper marker and exact 3904-byte wrapper geometry, then independently validates the embedded raw PS1 card. The downloadable .mcr payload is the exact source byte range after the wrapper; SaveEditor does not rewrite the GME header or repair the card.
Emulator & Retro Tools
PS1 DexDrive GME Container Extractor
Validate a complete DexDrive GME memory-card wrapper and extract its exact embedded 128 KiB PS1 card only when the 123-456-STD marker and every embedded card checksum pass.
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.

Platforms
PS1
Supported versions / editions
DexDrive GME complete PS1 memory-card images using the documented standard wrapper.
Input constraints
Exactly 134,976 bytes; fixed 123-456-STD marker at offset 0; exactly one 128 KiB embedded card beginning at offset 3904; embedded MC header checksum plus all 15 directory checksums valid.
Known limitations
Read-only inspection/extraction only. No repair, padding, truncation, checksum regeneration, resigning, wrapper rewriting, game payload editing, metadata synthesis, or extension-only acceptance.
Output / result
Exact 131,072-byte embedded raw PS1 memory-card source range plus a deterministic JSON inspection report.
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 original .gme file. SaveEditor validates the wrapper and embedded card, then offers only the exact embedded card byte range for download.
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.

Operational
Tool-specific privacy notes
Phase 55 reads only the explicitly selected local wrapper/container in the browser. The container-intelligence-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. The selected source is never modified, and successful payload extraction is restricted to a strictly validated exact source byte range.
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 marker, wrong total size, truncated wrapper, or any embedded card checksum failure causes fail-closed refusal.
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 valid/invalid wrapper fixtures, exact payload-range equality checks, source immutability, malformed/truncated refusal, no-network static checks, independent reference reconstruction, and full historical 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 DexDrive GME Container Extractor 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.
