This directed mapping accepts only a canonical VGS source, proves its exact raw card, writes the documented canonical GME form, and verifies both target payload equality and a byte-identical reconstruction of the original VGS source.
Emulator & Retro Tools
PS1 VGS to DexDrive GME Migrator
Losslessly migrate a canonical VGS/MEM card to canonical DexDrive GME through an exactly preserved raw 128 KiB card state, with source reconstruction and target reopen proofs.
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

Platforms
PS1
Supported versions / editions
Canonical VGS/MEM -> canonical DexDrive GME, preserving the raw PS1 card exactly.
Input constraints
Canonical VGS/MEM source only; strict embedded card checksums/chains; deterministic canonical GME target; exact rollback-source reconstruction.
Known limitations
Lossless canonical-representation migration only. Non-canonical VGS/GME wrapper metadata, ambiguous versions, invalid PS1 checksums/chains, lossy field mappings, checksum regeneration, game-payload editing, source mutation, signing/encryption work, and guessed game-specific version upgrades are refused.
Output / result
Canonical GME target, exact VGS rollback source, and deterministic SHA-256-bound migration 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 VGS/MEM source. SaveEditor validates both representations around the unchanged raw-card payload before downloads are enabled.
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 56 performs migration entirely in the browser on the explicitly selected local file. The migration-v1 runtime has no fetch, XMLHttpRequest, WebSocket, sendBeacon, FormData upload, server-side save processing, or telemetry path. The permanent 16 MiB ceiling remains in force. The selected source is never mutated; output is authorized only after exact raw-payload preservation, strict target reopen, and byte-identical rollback reconstruction are all proven.
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
Unknown VGS metadata or any PS1 structural failure refuses migration rather than discarding or repairing data.
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 an independent implementation of the documented VGS/GME writers, deterministic raw-card fixtures, exact target byte vectors, strict source/target reopen, source immutability, byte-identical rollback reconstruction, SHA-256 binding, malformed/non-canonical refusal, no-network static checks, 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 VGS to DexDrive GME Migrator 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.
