The King of Fighters XIII Cheats

The following characters have a 2nd scheme when you hit the "Back" button as you select them: 1. Kyo Kusanagi (Original School Uniform) 2. Yuri Sakazaki (Original Long Braids) 3. Elizabeth Blanctorche (KOFXI Outfit) 4. Joe Higashi (Tiger stripes Outfit) 5. Andy Bogard (KOF2001 Outfit/ Eiji Kisaragi alternate.) 6. Takuma Sakazaki (Mr. Karate outfit) 7. Raiden (Big Bear outfit) 8. K' (More colors, including his arcade famous "UNO" colors.) 9. Ralf Jones (Camouflage outfit) What's more for the characters with literal alternate outfits, you can actually edit said alternates in Customize mode as well.

Two characters actually have alternate costumes, Kyo and Takuma to be exact. To use them simply select them and press the back button when you're about to select a costume colour. Doing this for Kyo lets you play as him in his classic costume he wore before KoF 99 (headband with short sleeved jacket), doing this for Takuma lets you play as him wearing his Mr. Karate mask.

In order to use two of the console exclusive characters Billy Kane and Saiki, you must meet a certain number of TAs (Target Combos) before reaching Stage 4 in Arcade mode. Take note earning TAs only count if you defeated your opponent so fallen team members' TAs won't carry over.

Play Arcade Mode until he challenges you to a fight. Defeat him and he will be unlocked.
