The King of Fighters 2003 (Japan, JAMMA PCB)

Like The King of Fighters 2002, this game reverts back to the old 3-on-3 format used from KOF '94 to KOF '98. A new feature to this game that old-school KOF fans might have trouble getting used to is the new interchangeable team system. You still pick three characters and decide your character order before a match, but now you have the option to change to another character during a match. You can change at any time during a match, but you cannot when two of your teammates have been taken out, and only one character is left in reserve.
