How to Play 2 Games in One! Marble Madness + Klax
Quick start
Choose Marble Madness or Klax from the compilation menu. In Marble Madness, press START at its main menu and roll the blue marble to the GOAL before time expires; take a direct route first and use a speed burst only for steep ramps. In Klax, highlight New Game and press START or A, then catch falling tiles and drop three or more matching colours in a vertical, horizontal or diagonal line.
Controls
Compilation menus use the D-pad and A/START. Marble Madness: D-pad rolls the marble, A or B gives a speed burst, and START pauses/resumes. Klax: Left/Right moves the paddle, Down temporarily speeds incoming tiles, A drops the collected tile, B throws it back onto the conveyor, and START pauses/resumes. High-score initials use Up/Down and A.
