DracoFighter is playable with only 4 buttons: Left, Right, A, and B. There is sometimes a 5th button mentioned called C, but it's essentially just a macro for A+B.
Left/Right will more commonly be referred to as Back/Forward, since attacks will be dependent on which way your character is facing. When referring to moves, A will be referred to as Attack, B will be referred to as Special, and C will be referred to as Grab.
For those more familiar with numpad notation, these will also be included as alternative notation in move overviews:
Numpad notation uses numbers to describe directions in accordance to their location on a numpad. This list assumes the player is on the P1 side. if on the P2 side, mirror the inputs horizontally. 9 becomes 7, 6 becomes 4, etc.
In-game, moves will be referred to as e.g. F-Attack, which is Forward + Attack. You may also see B-Special (Backward + Special), or even N-Grab (Neutral + Grab), where N stands for Normal or Neutral -- this refers to not pressing any direction (5 in numpad notation).
