Mega Man Battle and Chase Cheats

Mega Man Battle and Chase Quick Start
For a quick start, use Quickman's design (the V-like item in his car.) Hold X after the first light.

Mega Man Battle and Chase Secret Car
Keep racing against your opponents until a sign appears saying "HERE COMES A NEW CHALLENGER." Beat the challenger to receive one part of the secret car. Continue to do this until you've collected all four parts.

Here's where to find them:

DESIGN  - NAPALMAN'S STAGEWHEELS  - QUICKMAN'S STAGEBOOSTER - ICEMAN'S STAGEBODY    - GUTMAN'S STAGE

NOTE: The locations above work for all characters except for Gutman, Quickman, Iceman, and Napalman.
