[ EXECUTION PROTOCOL ]

How to Convert MCR to ZIP Locally

  1. PHASE 01 // STAGE SOURCE

    Load .mcr Payload

    Drag and drop your .mcr file onto the working surface or use the system file dialog. File magic bytes are verified locally on device.

  2. PHASE 02 // CONFIGURE

    Set Codec & Quality Parameters

    Select a quality preset (Lossless, Visually Lossless, Balanced, Smallest) or adjust advanced encoding switches in the options panel.

  3. PHASE 03 // COMPILE & EXPORT

    Export .zip to Disk

    Click CONVERT to execute local WebAssembly compilation. Save the finished .zip directly to local storage, or stage it for chaining.

Technical Details & FAQ

[?]What is an .mcr file?

An .mcr file is a raw 128KB flash memory dump of a Sony PlayStation 1 Memory Card, containing 16 blocks of 8KB storing game saves, product IDs, and custom 16x16 icon graphics.

[?]What is an .mcs file?

An .mcs file is the universal single-game save format containing a 128-byte directory frame followed by save data blocks. It can be imported directly into DuckStation, Mednafen, and real PS1 memory cards using MemcardRex or DexDrive.

[?]Are DexDrive and RetroArch saves supported?

Yes. DexDrive headers (131,136 bytes), standard raw images (131,072 bytes), and emulator saves (.mcd, .srm, .vmp) are automatically detected and parsed.

[?]Are memory card files uploaded anywhere?

No. All block scanning, icon palette decoding, and ZIP archiving execute 100% locally in your browser memory.

[?]Why convert from MCR to ZIP?

MCR Document (MCR) and ZIP Document (ZIP) serve distinct roles across the digital workflow. Converting to ZIP provides optimized compatibility, modern compression efficiency, or standardized playback across web browsers, operating systems, and media production environments.

[?]Is the MCR to ZIP conversion lossless or lossy?

The output format (ZIP) is inherently lossless or supports lossless operation. Your original visual or audio fidelity is mathematically preserved without quantization artifacts.

[?]Does convrtr upload my files to any cloud server?

Never. convrtr is architected with a strict zero-upload model. All processing, decoding, decompression, and encoding happen 100% locally on your machine using sandboxed WebAssembly and Web Workers. Your data never touches an external server, database, or analytics collector.

[?]How can I convert MCR to ZIP from the terminal / command line?

You can execute this conversion locally via command-line utilities such as ffmpeg, cwebp, or ImageMagick. For example: see the developer terminal recipe provided in the technical specifications dossier above. convrtr provides the identical local-first capability directly inside your browser without installing CLI packages.

[?]Can I batch convert multiple MCR files to ZIP simultaneously?

Yes. You can drop multiple .mcr files into the instrument to process them concurrently in browser Web Workers, or click 'Open in Master Studio' to queue mixed formats, configure individual targets, and export as a single ZIP archive.
