I found this error in the Cheats section of the GameWinners.com website. The cheat says if you complete Arcade Mode three times, you will unlock all the Tekken 5 stages in Versus Mode. Well, I bought the game recently and downloaded it into my PS3 hard drive. I found out that the Tekken 5 stages are actually unlocked after beating Arcade Mode six times not three times. Also, not only can you select these stages in Versus Mode but you can select them in Practice Mode as well.
