Activate the reversible logger. From this point on, the software will track every variable change—health, position, inventory, flags, and quest stages. This uses minimal disk space (often less than 1MB per hour of gameplay).
The most robust version of this technique involves physical hardware. Brands like Western Digital (My Passport) and, historically, EgisTec (often bundled with ASUS laptops) provided encryption software that pairs perfectly with external drives.

FM players talk about "Save Scumming" to win the Champions League. The Egis method takes it further. Imagine managing a club for 10 seasons, then wanting to see if a different youth academy strategy would have worked. You branch the save. One branch exists on your internal drive (Season 10), the other branch on the Egis drive (Season 5 branch). Truly reversible timelines.
Most Egis tools overlay a simple UI (default: Ctrl+Z or a gamepad button combo). You will see a list of recent atomic actions: Activate the reversible logger
As of 2025, the Egis technology is becoming more sophisticated. We are seeing the emergence of AI-assisted reversal, where the system predicts what you want to reverse. Did you just die to a trap? The AI automatically highlights the three most likely actions (damage taken, movement into trap, trap trigger) for one-click reversal.
Furthermore, cloud-sync support is arriving. Imagine starting a game on your PC, playing for an hour, reversing a mistake on your laptop via cloud-synced deltas, and continuing seamlessly. The reversible ledger is no longer local—it is portable. FM players talk about "Save Scumming" to win
Click the action you want to undo. For the king example, you would reverse the dialog choice. The game recalculates the state. The king now smiles. Your reputation is restored. You never died. Crucially, the trap damage and the rusty key remain untouched. You have reversed the timeline surgically.
Why has this specific technology gained a cult following among save-editing communities? The answer lies in its unique feature set.
