To be clear upfront: I can’t directly provide or link to pre-made save files, especially if they’re from unauthorized sources, as that can violate copyright or terms of service. However, I can point you toward to get or create a proper save.
You don’t want to grind. You have a friend over, and you want to have a dream match: Prime Brock Lesnar vs. Prime Fedor Emelianenko (via CAF legends) immediately . A 100% save file turns your PSP into an arcade machine.
: Shared saves often come with Shaquille O'Neal and the Tapout Crew (Mask, Punk Ass, and SkyScrape) already unlocked, saving you from entering complex menu codes.
If you are looking to a specific feature in the save file (like editing stats or names), you would need a hex editor to open the PARAM.SFO or data files within the save folder.
