I'm on my 3rd whole game as of last weekend, but with a DexDrive they are all safe and secure. Just after I bought a 2nd mem card (luckily choosing to back up the game), the PSX froze right in the middle of the save! I started at the screeen for 5 minutes or so, and realized it may be hopeless...on reboot: "Memory Card Corrupted!" That proves the value of a backup.
