How to Save Your Progress in Retro Games: A Complete Guide
Learn about password systems, battery saves, save states, and other methods retro games used to preserve your progress — and how to use them today.
The Art of Saving (When There's No Save Button)
Modern gamers take saving for granted. Auto-save, quick-save, cloud saves — our progress is always protected.
Retro games were different. Limited memory and hardware constraints meant creative solutions were necessary. Understanding these systems is essential for enjoying classic games.
The Different Save Methods
1. Password Systems
How it works:
At certain points (level completion, checkpoints), the game gives you a code. Write it down, enter it later, and you resume from that point.
Example games:
- Mega Man series
- Metroid (NES)
- Kid Icarus
- Castlevania II
Tips for password games:
- Take photos — Use your phone to capture password screens
- Double-check — One wrong character means starting over
- Know the format — Some use letters only, others mix numbers and symbols
- Watch for confusing characters — Is that an O or a 0? An I or a 1?
Famous password: Metroid's "JUSTIN BAILEY" — Try it and see what happens!
2. Battery-Backed Saves
How it works:
Cartridges contained a small battery that maintained save data even when powered off. These work like modern saves.
Example games:
- The Legend of Zelda
- Final Fantasy
- Pokemon series
- Chrono Trigger
The problem today:
Original cartridge batteries die after 15-30 years. Many vintage games have lost their save functionality.
Modern solutions:
- Replace the battery (requires soldering)
- Use reproductions with new batteries
- Play via emulation (no battery concerns)
3. No Saves at All
How it works:
You don't save. You beat the game in one sitting, or you start over.
Example games:
- Contra
- Ghosts 'n Goblins
- Super Mario Bros
- Most arcade-style games
Strategies for no-save games:
- Practice individual sections — Master early levels to breeze through them
- Use continues wisely — Some games offer limited continues
- Leave the console on — Pause and take breaks (risky with old hardware)
- Accept the challenge — This is how they were meant to be played
4. Save States (Emulation)
How it works:
Emulators can "snapshot" the game's exact state at any moment. You can save anywhere, anytime, and return instantly.
Advantages:
- Save before difficult sections
- Experiment without risk
- No lost progress
Disadvantages:
- Can feel like cheating
- Reduces tension and achievement
- Doesn't teach you to master the game
Recommended approach: Use save states for learning, but challenge yourself to beat games without them eventually.
Game-Specific Save Guides
The Legend of Zelda (NES)
Save method: Battery save (hold UP+A on 2nd controller and press START to save)
What saves:
- Current heart containers
- Inventory items
- Dungeon completion status
- Triforce pieces
What doesn't save:
- Position (you restart at the start point)
- Rupees partially (keeps some)
Tip: Save before entering dungeons to preserve your progress before boss fights.
Metroid (NES)
Save method: Password (shown on game over screen)
What saves:
- Collected items (missiles, energy tanks, beams)
- Defeated bosses
What doesn't save:
- Exact position
- Current energy/missiles (start with 30 energy)
Tip: Write down passwords after collecting important upgrades, not just at death.
Mega Man Series (NES)
Save method: Password (shown after stage completion)
What saves:
- Defeated Robot Masters
- E-Tanks collected
- Special weapons
What doesn't save:
- Lives (start with 3)
- Stage progress
Tip: The password you get after a stage is the same regardless of path. Plan your preferred stage order.
Pokemon Series (Game Boy)
Save method: Battery save (one save slot only)
What saves:
- Everything (position, Pokemon, items, progress)
Critical warning: Only ONE save file exists. Starting a new game will eventually overwrite your save.
Tip: Multiple save files require multiple cartridges (or emulation).
Final Fantasy (NES)
Save method: Battery save (at inns and tents)
What saves:
- Character stats and equipment
- World map position
- Quest progress
What doesn't save:
- Dungeon position (you restart at entrance if you die)
Tip: Always save before entering dungeons. They can be long and brutal.
The Philosophy of Limited Saves
Why Didn't They Just Add Saves?
Technical limitations:
- Memory was expensive
- Cartridge space was limited
- Battery-backed RAM added cost
Design philosophy:
- Challenge was part of the experience
- Games were meant to be mastered
- Arcade heritage valued skill and memorization
The Hidden Benefits
Limited saves actually improved games in some ways:
- Higher stakes — Every life mattered
- Deeper mastery — You learned to play well, not just progress
- Memorable moments — Finally beating a tough section felt incredible
- Community bonding — Sharing strategies and passwords connected players
Modern Approaches to Old Challenges
If You Want the Authentic Experience
- Don't use save states
- Write down passwords the old-fashioned way
- Accept that you might not finish in one sitting
- Appreciate the challenge as intended
If You Want a Balanced Experience
- Use save states sparingly (beginning of levels, before bosses)
- Try sections without states first
- Consider it a "practice mode" for eventual real runs
If You Just Want to Experience the Games
- Use save states freely
- No judgment — the games are still worth experiencing
- You can always challenge yourself later
Save State Etiquette (For Yourself)
If you use save states, consider these guidelines:
Less Intrusive:
- Save at the start of new levels/areas
- Save after major accomplishments
- Load only when you would have genuinely game-overed
More Intrusive:
- Save before every difficult jump
- Save mid-boss-fight
- Save-scum through RNG sections
Neither is wrong — just be honest with yourself about the experience you want.
Practical Tips
Organizing Passwords
Create a system:
- Dedicated notebook
- Notes app with game-specific pages
- Photos organized by game
Protecting Battery Saves
For original cartridges:
- Don't leave games in the console when not playing
- Store in cool, dry conditions
- Check battery status periodically (dim save screens = dying battery)
Emulator Save Management
- Create multiple save states at different points
- Name or number them meaningfully
- Don't overwrite your only state accidentally
Conclusion
Understanding how to save in retro games is essential for enjoying them. Whether you embrace the challenge of password systems and limited saves, or use modern conveniences like save states, the key is finding an approach that lets you appreciate these classic experiences.
The games were designed with their limitations in mind. Those limitations shaped the design. Understanding that context enhances our appreciation even as we adapt our approach for modern play.
