Checking Cartridge Authenticity
How to check your game cartridge for counterfeit markers using Playback.
3 min read
The easiest way to check your game cartridge is to insert it into your Operator device. Playback automatically checks for counterfeit markers by analyzing the internal hardware and game data against our database of known releases.
How it works
When you insert a cartridge, Playback:
- Reads the game data from the cartridge
- Analyzes the cartridge’s hardware characteristics
- Displays the authenticity status on the Play tab
This process happens automatically — just insert your cartridge and look at the result.
Understanding the results
| Status | What it means |
|---|---|
| Official | Matches known official release in our database. No typical counterfeit markers detected. |
| Unofficial | The cartridge is a reproduction, flashcart, or homebrew game. This doesn’t mean it won’t work — many unofficial cartridges play fine. |
| Unrecognized | Playback couldn’t verify the cartridge. This may indicate a counterfeit, a regional variant not in our database, a rare/obscure title, or dirty cartridge pins causing a false positive. |
What to do with each result
Official
Your cartridge matches a known official release and shows no counterfeit markers. You can:
- Play with confidence
- Trust the save functionality
Unofficial
Your cartridge is a reproduction, flashcart, or homebrew, but it may still work:
- Homebrew games and flashcarts show as Unofficial
- Reproduction cartridges may have save issues — see Rewritable Cartridge Save Issues
- The game should still be playable
Unrecognized
This needs further investigation:
- Clean the cartridge pins — Dirty contacts can cause read issues. See Cleaning Cartridge Contacts.
- Check if it’s a regional variant — Japanese or European versions may not be in our database yet
- Inspect the cartridge physically — See Spotting Fake Games for visual inspection tips
- It may be counterfeit — If you bought it secondhand, it could be a reproduction
Why authenticity matters
Save reliability
Official cartridges use quality components with predictable behavior. Reproduction cartridges often have modified save mechanisms that can corrupt your progress.
Resale value
If you’re collecting or plan to sell games, knowing authenticity affects value significantly.
Peace of mind
Checking your childhood collection or verifying a recent purchase gives you valuable information about what you own.
Limitations
Playback’s authenticity check is very accurate, but:
- Very high-quality reproductions may occasionally fool the system
- Regional variants or obscure titles may show as Unrecognized
- The check verifies game data and hardware, not the physical shell
For the most thorough verification, combine Playback’s check with physical inspection.
