Mymc Memory Card -

is a public domain PC utility designed to manage PlayStation 2 (PS2) virtual memory card images ( ), primarily for use with the PCSX2 emulator

It allows you to import and export save files between your computer and virtual memory cards, making it essential for users who want to use game saves downloaded from sites like GameFAQs or move their own progress between an emulator and a real console. Key Features and Functionality Import/Export Formats

: It supports a wide range of PS2 save formats including MAX Drive ( ), SharkPort ( ), X-Port ( ), and Code Breaker ( Virtual Card Management

: You can use it to create new memory card images, view the contents of existing ones, and delete specific save files. Graphical Interface

: While it includes a command-line tool for advanced operations, it is most commonly used via its simple GUI (mymc-gui.exe) for ease of use. Compatibility

: Original versions were Windows-exclusive, but newer forks like

have been ported to Python 3 for cross-platform support and compatibility with modern hardware like the MemCard PRO2 University of Waterloo How It’s Used mymc, a PS2 Memory Card Image Utility

While mymc might just look like a utility for managing PlayStation 2 memory card images, it has become a "digital archaeologist’s" favorite tool for uncovering forgotten gaming histories. The "Time Capsule" Effect

Because PS2 memory cards required users to manually delete each file, many owners simply sold their cards with years of progress still intact. Collectors and YouTubers now use mymc to peer into these 20-year-old "digital time capsules".

Frozen in Time: One popular trend involves buying bulk lots of used cards to see the last time a game was played—sometimes revealing a final save from a Christmas morning decades ago.

Finishing the Journey: Some "digital archaeologists" use mymc to export these saves into emulators like PCSX2 to finish a stranger's game, finally completing a level or boss fight that someone gave up on in 2004. The Hidden Art of Save Icons

One of the most interesting aspects found when using mymc to browse old cards is the 3D animated icons. mymc memory card

Unlike modern static images, PS2 saves were actually tiny 3D models.

The "Secret" Animations: In games like Onimusha 2: Samurai's Destiny, the save icon changes based on what you do; if you try to delete or copy the file, the character model might perform a death animation or cut down a pole. Tools like mymc allow fans to extract and preserve these quirky pieces of digital art. The Modder's Key

For the homebrew community, mymc isn't just for nostalgia—it's a gateway to unlocking the console's full potential.

FreeMCBoot: It is frequently used to inject exploits like FreeMCBoot or Mecapone into virtual memory card images.

Reviving the Dead: Modders use it to bypass broken disc drives by setting up USB loading through the memory card, effectively bringing "dead" consoles back to life.

Are you looking to import a specific save file or are you trying to recover data from an old memory card image?

ps2dev/mymc: A public domain utility for working with ... - GitHub

mymc is a public domain utility designed to manage PlayStation 2 memory card images (.ps2). It is primarily used by enthusiasts of the PCSX2 emulator to import and export save files.

The tool serves as a critical bridge between modern PC storage and the proprietary file systems of the vintage console. 🛠️ Core Functionality

At its heart, mymc acts as a file explorer for virtual memory cards. It allows users to manipulate the raw data inside an emulator's "card" without needing to boot into the PS2 BIOS.

Importing Saves: Supports multiple legacy formats including MAX Drive (.max), EMS (.psu), SharkPort (.sps), X-Port (.xps), and Code Breaker (.cbs). is a public domain PC utility designed to

Exporting Saves: Users can extract their progress from a virtual card into .psu or .max formats for backup or sharing on platforms like GameFAQs.

Card Creation: The tool can generate new, empty virtual memory cards, including non-standard sizes larger than the original 8MB.

File Management: It provides a directory view to see exactly which game occupies which "folder" on the card, allowing for manual deletion of corrupt or unwanted files. 💻 Modern Iterations and Evolution

The original mymc (created by Ross Ridge) was written in Python 2 and used an aging GUI library. Because it is public domain, several modern forks have emerged to keep it compatible with modern operating systems and hardware: myMCpp A modern, open-source rewrite of the tool in C++.

Stability: Offers better performance and stability on Windows 10/11.

Advanced Features: Includes a command-line interface (CLI) for batch processing and error checking like ecc_check to validate file system integrity.

Format Support: Adds support for .mc2 files used by hardware like the MemCard PRO2. mymc++

Another revised version that focuses on usability improvements and bug fixes for the original code, specifically catering to users of newer PS2 hardware mods. 📂 Technical Deep Dive: The PS2 File System

The creator of mymc extensively researched the PS2's NAND flash memory layout to make the tool possible. Notable technical quirks include: Use PS2 save files In PCSX2 with MYMC | Tutorial

The "paper" you are likely referring to is a technical document titled "PlayStation 2 Memory Card File System" written by Ross Ridge, the original creator of the mymc utility. It serves as a comprehensive (though unofficial) guide to the internal structure and layout of PS2 memory cards based on the research conducted to develop the software. Key Details from the Technical Paper

Purpose: It describes the file system layout for PlayStation 2 memory card images (.ps2), which are primarily used by emulators like PCSX2. Step 3: Convert Between Formats

Format Foundations: The document covers the basics of NAND Flash memory, glossary terms for the file system (like clusters and blocks), and data storage in little-endian byte order.

Naming Conventions: Since there is no official public documentation from Sony, many of the field names and structure labels in this paper were created by the author to define how the data is organized. Overview of mymc Software

While the paper explains the "how," the mymc software is the practical tool that applies those rules.

Capabilities: It allows users to import and export save files between virtual memory cards and common formats like MAX Drive (.max), EMS (.psu), and Code Breaker (.cbs).

Virtual Memory Support: It can create new, blank memory card images and manage their contents, such as adding or deleting individual files. Modern Variants:

mymc+: A Python 3 port that adds support for PlayStation 3 (.psv) save files.

mymc++ / myMCpp: Modern versions that support the MemCard PRO2 (.mc2 files) and include native C++ rewrites for better stability.

You can find the original paper and utility on the official mymc website or browse the source code on GitHub. mymc, a PS2 Memory Card Image Utility


Step 3: Convert Between Formats

  • .mcr.psu (for PS3/PSX adapter)
  • .mcr.gme (for DexDrive hardware)

Example:

mymc.exe mycard.mcr convert mycard.psu psu

Step C: Importing Saves (Moving Saves to Emulator)

If you downloaded a save file from the internet:

  1. Format Compatibility: Ensure the file is in a supported format (.psu, .max, .cbs, .xps). If the file is a .zip or .rar, extract it first to get the actual save file.
  2. Open your memory card in mymc.
  3. Click the Import button (icon with an arrow going into the drive).
  4. Navigate to where your downloaded save file is located.
  5. Select the file and click Open.
  6. mymc will process the file and add it to the memory card list.
    • If a save with the same name exists, it will prompt you to overwrite it.

10. Troubleshooting Common Issues

  • Corruption after unplug: Ensure unmounting or implement journaling+atomic commits; investigate power supply decoupling.
  • Slow writes after heavy use: Controller background garbage collection; avoid continuous high-write workloads or provision higher-endurance cards.
  • Card not recognized: Check signal voltage, contact pads, and SD/MMC mode negotiation (CMD8/ACMD41). For SPI mode, verify proper CS and clocking.
