One of the biggest limitations of the original physical PS2 memory cards was space; they only held 8 megabytes of data. Create-A-Superstar files in WWE SmackDown! games are notoriously large because they store complex 3D asset configurations, move-sets, and logic data. A single memory card might only have room for a handful of heavily detailed CAWs.
These utilities allow you to open a .ps2 memory card file, look at the individual save blocks (such as the specific save file for Here Comes the Pain ), and export or import them individually. This allows you to mix a 100% completed SmackDown! save with your personal saves from other genres, like Grand Theft Auto or Final Fantasy , without conflicting files. Mcd001.ps2 WWE Smackdown
