Action Replay PS1 "Spring": What It Means & How It Worked

"Spring" isn't a game — it refers to activating (springing) cheat codes via the Action Replay cartridge for PlayStation 1.

Action Replay PS1 Basics

• Form Factor: Cartridge inserting into PS1 memory card slot (later versions: CD-boot disc + memory card dongle).
• Function: Intercepts RAM at boot; lets you enable pre-loaded or manually entered codes.
• Common Codes: Infinite health/lives/ammo, unlock all levels/characters, moon jump, debug menus.

Usage Flow

1. Insert Action Replay cartridge.
2. Power on PS1 → Action Replay menu loads.
3. Select game (auto-detect or manual).
4. Enable desired codes.
5. Press "Start Game" (or swap disc via eject trick on early models).

Caveats

• Codes can crash games, corrupt saves, or break triggers.
• Not all games supported; code databases varied by region (NTSC-U/J/PAL).
• Original hardware only — does not work on PS2/PS3 backward compatibility.

Today: Used on eBay/retro shops. For emulation (DuckStation, PCSX-R), use built-in cheat menus (Pnach/Action Replay format) instead.
