Simple. Accelerating is up arrow and steering is left and right arrows. For P2 accelerating is W and steering is A and D. The start screen will show you what to press for P1 and P2 to get characters( numbers are player 1 and letters are player 2). F for next racecourse. Characters are: Mario Luigi Peach Bowser Bowser Jr. Wario Waluigi.( yes, I know he is popular with memeists)
my base was 'racing' in the Usborne book for beginning scratch,so thanks to the author of that book.everything else is mine. Except for the rights to the characters and all that. IMPORTANT NOTICE! I will regularly post highscores for each track, but only if you list which track you were racing on! Now enough reading. Start racing!
