Mega Man Battle & Chase/Unlockables

Dr. Wily
Every time you beat Dr. Wily, not only you can get one of his parts, but also some contents will be unlocked in Versus and Time Attack Modes. You have to beat Dr. Wily with the same save file and racer one, two, three or four times in Grand Prix mode.

If you win a Grand Prix circuit without losing any of the races, you will unlock a karaoke mode.

Duo & the Black Challengers
After you beat Dr. Wily, the Black Challengers will start appearing in Grand Prix mode. Tap a button (different recipes exist) while the starter lights are turning on, and a new challenger appear. They will appear always in the same order, regardless of the courses you are in.


 * 1) Black Joe
 * 2) Black Devil
 * 3) 4 Black Roaders
 * 4) All of the above

Every time you win one challenge, the defeated racer(s) will tell you a secret technique. Furthermore, an extra part will become available in a specific course. You have to collect the hidden question mark and win the race in order to obtain the extra part.

If you collect all four extra parts, Duo will become available in Versus and Time-Attack modes.

Notes:
 * Duo's Hard Grandeur and the car made of the four extra parts are different.
 * The parts of Duo's car cannot be obtained in Grand Prix mode.
