Resident Evil 4 Aethersx2 Save Data
Resident Evil 4: AetherSX2 Save Data Guide Resident Evil 4 is widely considered one of the best ports of the PlayStation 2 era. Running it on Android via the AetherSX2 emulator (and its spiritual successor, NetherSX2) allows players to experience the game with upscaled resolutions and texture filtering far superior to the original hardware. However, managing save files—whether importing a completed game to unlock professional mode or backing up your progress—can be tricky due to the emulator's file structure. This guide covers where to find save files, how to import them, and troubleshooting common issues.
1. Where to Place Save Data (The Directory) AetherSX2 stores save data in a specific folder on your Android device's internal storage. If the emulator cannot find the files, it is usually because they are placed in the wrong directory. The File Path:
Open your device's File Manager . Navigate to your Internal Storage (not SD Card, usually). Look for a folder named AetherSX2 . Open the memcards folder.
Full Path: Internal Storage/AetherSX2/memcards/ Inside this folder, you will typically see a file named Mcd001.ps2 . This acts as the virtual Memory Card for Slot 1. resident evil 4 aethersx2 save data
2. How to Import Downloaded Save Data If you have downloaded a save file from the internet (e.g., a "100% Complete" file to unlock the Chicago Typewriter or Infinite Launcher), it will usually come in one of two formats: .ps2 (Raw Memory Card) or .cbs /.max` (CodeBreaker/Action Replay formats). Method A: Using the .ps2 file (Easiest) If the downloaded file is already named something like Mcd001.ps2 :
Rename your current Mcd001.ps2 file in the memcards folder to Mcd001_backup.ps2 (to save your old progress). Copy the downloaded file into the memcards folder. Ensure the new file is named exactly Mcd001.ps2 . Launch AetherSX2 and start Resident Evil 4. The game should now read the new memory card.
Method B: Using the Native Import Feature (For .cbs / .max) If the file is compressed or you want to import it into your existing memory card without overwriting other saves: Resident Evil 4: AetherSX2 Save Data Guide Resident
Open AetherSX2 . Tap the three lines (Menu) in the top left. Go to Settings > Memory Cards . Select Slot 1 . Tap Import . Navigate to your download folder and select the save file. The emulator will convert and inject the save into your current memory card file.
3. Creating "Save States" vs. "Memory Card Saves" In Resident Evil 4, it is vital to understand the difference between these two methods, as they are not interchangeable.
Memory Card Saves (In-Game): These are the "typewriter" saves found within the game. They are safe, stable, and transferable to other emulators or real PS2 hardware. Always keep these as your primary backup. Save States (Emulator): These are "snapshots" of the exact moment in the game, accessed via the AetherSX2 menu (Save Slot 1-10). Warning: Save States in Resident Evil 4 on PS2 emulation can be buggy. Loading a save state during a cutscene or inventory transition can corrupt your data. This guide covers where to find save files,
Best Practice: Use Save States for quick retries during difficult combat sections, but always save at a Typewriter afterward to ensure your progress is secure on the virtual Memory Card.
4. Troubleshooting Common Issues "The save file is corrupted" This is a common error in RE4 if the region of the save data does not match the region of your game ISO (ROM).
