Saving in Project64 (N64 Emulator): In-Game Saves vs Save States

Project64 doesn't auto-save like modern emulators. Two systems:

1. In-Game Saves (Cartridge SRAM/EEPROM/FlashRAM)

• Most N64 games save to virtual cartridge memory.
• Use in-game menu: Save, Write, Controller Pak.
• Files: .sra (SRAM), .eep (EEPROM), .fla (FlashRAM) in Save folder.
• Back up this folder.

2. Save States (Emulator Snapshots)

• Instant full-state capture (RAM, CPU, GPU, audio).
• Default: F5 (save slot 0), F7 (load slot 0). F6/F8 cycle slots.
• Files: .pj in SaveStates folder.
• Not portable across emulator versions.

Best Practice

1. Use in-game saves for progress.
2. Use save states for checkpoints (boss attempts, RNG manipulation).
3. Export battery saves: File → Export Battery File (for real hardware/other emus).
4. Configure: Options → Settings → Save → "Auto-save battery" on close.

Controller Pak (Mem Pak)

• Separate .mpk files per game.
• Enable in Options → Controller → "Controller Pak" → "Plugged."
• Game must support it (many do).

Never rely solely on save states — corruptible, version-locked.
