Analysis: Sonic Riders: Zero Gravity (PS2) — Save File

Required tools & inputs

• A PS2 memory card reader (for PC) or an emulator (e.g., PCSX2) with virtual memory card export/import.
• Hex editor (HxD, 010 Editor).
• Binary diff tool (vbindiff, bsdiff) for comparing saves before/after actions.
• Scripting language (Python) for automating parsing and checksum recompute.
• Optional: 010 Editor with a custom binary template if you create one.

Overview

Sonic Riders: Zero Gravity on PlayStation 2 uses standard PS2 memory card save files (.PS2 / raw memory card blocks) to store player progress, unlocked content, high scores, and custom rider data. A save-file analysis aims to identify the file structure, offsets for key fields (e.g., player progress flags, unlocked characters, race times, and cosmetics), checksums/validation routines, and any anti-tamper or copy-protection markers. Below is a dynamic, step-by-step plan and findings-oriented breakdown you can use to locate, inspect, and modify relevant save data safely.

5. Usage on Emulators (PCSX2)

• PCSX2 stores saves as memory card images (.ps2 format).
• Import individual saves using myMC (Memory Card Manager) or MymcAlpha.
• Drag/drop extracted save folder (e.g., SLUS-21770 folder) into open memory card via myMC.
• Emulator must be set to matching region BIOS.

Deliverables I can produce next

• Practical assistance options (pick one):
  1. A concrete differential-analysis walkthrough using two save files you supply.
  2. A Python script template to parse and patch likely fields, including CRC recompute (requires confirmed offsets).
  3. A 010 Editor binary template once the exact layout is mapped. Choose an option and provide save files (exported .mcr/.ps2) if you want hands-on mapping.
