EBA Mode

"The extra characters "Elite Beat Agents" and Neko (Cat) are available at DS Download Stations!"
 * - EBA Mode announcement, translated from Japanese

EBA Mode or Elite Beat Agents mode for short, is a special feature that was offered as downloadable content for Moero! Nekketsu Rhythm Damashii Osu! Tatakae! Ouendan 2, based on the titular game.

Content
EBA Mode gives Japanese Ouendan players an opportunity to experience Elite Beat Agents, the Westernized spiritual sequel to Osu! Tatakae! Ouendan, due to such game never being officially localized and released in the country. It comprises of skins based on the Elite Beat Agents and Elite Beat Divas for the 3-D dancing Ouendan on the touch screen, as well as two bonus multiplayer characters, Agent J and the Ramen Shop Cat, the latter which appeared in the first Ouendan game.

The former can be turned on or off in the single-player campaign mode by tapping the Elite Beat Agents badge icon on the difficulty selection screen before confirming the difficulty level. As the game initially ships without EBA Mode available to the player, the mode will be deleted from the game should a factory reset be carried out.

The following table shows which EBA character skins will be applied on which Ouendan 2 characters. In the penultimate mission of Ouendan 2, the first phase is performed by the Yuuhi Town Ouendan, which the Agents skins are applied to when EBA mode is turned on. Then the remaining two phases are performed by the Asahi Town Ouendan, whose leader is replaced by the Ramen Shop Cat, sporting their hairstyle, if the mode is turned on. In the final mission, which is performed by the leaders of both Ouendan, the Yuuhi Town Ouendan leader is replaced with their equivalent Elite Beat Agents leader, while the Asahi Town Ouendan leader is once again replaced by the Ramen Shop Cat.

Release
EBA Mode was offered as limited time downloadable content from DS Download Stations in Japan from June 28 to July 11, 2007, many weeks after Ouendan 2's initial release. However, due to the actual downloadable content being baked into the game code itself, it is possible to use a cheat device such as Action Replay to hack the game and activate EBA Mode even after the DLC was withdrawn from Download Stations.
