Kof 99 Plus Rom Exclusive Jun 2026

KOF '99 Plus ROM is an unofficial, enhanced "hack" version of the original Neo Geo arcade classic, The King of Fighters '99: Millennium Battle

In the original KOF '99, Kyo Kusanagi and Iori Yagami were "hidden" characters that often required the player to use the "Roulette" selection or achieve a high ranking. The KOF 99 Plus ROM simplifies this:

: The primary draw of "Plus" ROMs is making the final boss, Krizalid (both forms), immediately selectable on the character screen. It also typically unlocks Kyo Kusanagi and Iori Yagami without requiring the secret button codes needed in the original arcade version.
