MegaMan Battle Network 5 Double Team DS

MegaMan Battle Network 5 Double Team DS was, essentially, both versions of MegaMan Battle Network 5 packaged into one Nintendo DS game. It had a few new features, including the new "fuan" Emotional State. In this state, the Emotion Window would turn pink and the player would yell something into the microphone. If they succeeded, MegaMan would gain some randomly selected combination of two bonuses from instant Full Synchro, HP recovery or a barrier.

Extras
As stated above, it is both games combined into one. With these features also:

Bass Cross Gained by puting MMBN5-Team ProtoMan or Team Colonel with the Bass icon on the game.

Sol Cross Gained by outing Boktai 2: Solar Boy Danjgo (or Boktai 3 in the Japan version) in the GBA slot.

The Party Battle System In the non-cruitical parts of the plot, one can select two Navis on Lan's HP and one can than use it in battles.

Transport Chip A "Transport Chip", or TP Chip for short, can be used in Libertation battles. Basicly it switches an Navi with an corresponding one in other version (e.g. ProtoMan -> Colonel). There are 4 TP Chips.

Remixed Battle Music If one have a Battle Network 1, 2, 3, 4 or 4.5 game in the GBA slot, the game plays remixed battle music of that title.
