Hint: Basil The Bat Lord car parts:
Go to the circuit races and win all of them until reaching Johnny Thunder's
circuit. Win first place and the short FMV sequence showing that you won will
play. After that ends, go to build. Select "New Racer" or "Edit Racer". Select
Johnny Thunder's chassis, then go to "Quick Build". Keep pressing that option
until you get to the car with the "fire" in the back facing forward. Finally, go
to "Build" and press L2 or R2 until you get to Basil The Bat Lord's car parts.
You will not get Basil's character parts or chassis, only the car parts. Note:
This trick only works for J.T.'s chassis.
