Using a hex editor (HxD), open the save file and check:
If the checksum is invalid, the game will reject it at the verification stage.
To avoid losing progress to a bad verification, follow this 3-step backup strategy:

Pro tip: Always scan downloaded saves with PS2 Save Validator before copying to your memory card. Corrupt saves from untrusted sources will fail verification instantly.
The most compelling part of TTT save data, however, is the Ghost Data.
The PS2 version of TTT had a unique feature: it recorded your playstyle. If you inserted a memory card, the system would create a "Ghost" of your profile.

Today, retro collectors hunt for verified save files that contain "Legendary Ghosts"—save files from top-tier players from the early 2000s. Imagine finding a verified memory card from a famous arcade in Tokyo or California that holds the Ghost data of a pro player from 20 years ago. Loading that file allows a modern player to fight against the digital echo of a master from the past.

Preservation groups like the Internet Archive and niche PS2 preservation forums often have "Redump" verified memory card images (.PS2 files) that are bit-perfect copies of original cards.
A little-known trick: After unlocking a character (e.g., beating Arcade Mode with Heihachi), go to Options, then Save. Do it once, wait 5 seconds, then save again to the same slot. This redundancy forces the game to write a secondary checksum. Using a hex editor (HxD), open the save file and check:
Third-party memory cards are notorious for corruption. Sony's MagicGate cards are the most reliable for Tekken Tag Tournament.
If the message gets stuck, repeats, or the game doesn’t recognize your progress:

Those five seconds were sacred. They were the time to trash-talk your friend sitting next to you on the floor. The time to adjust your grip on the grey DualShock 2. The time to whisper, “You’re about to get Law’d.”
