After becoming a police member go to numero uno's clubhouse outside will be you after defeating him you get illegal robot (majel)
Custom Robo Arena happened in 2006.
Custom Robo Arena was created on 2006-10-19.
In school go to your clubhouse and your shadow self should be outside (after completing the game)
there arent any codes on custom robo arena
In the Clubhouse, go to the back left crate, its there
look for your robo if you have all the movies then find it and it will help you.
You go to neo brain on the first floor speak to the people at the desk and press BUY and then you will find it
yes there is
no
Since Custom Robo Arena can be played on DS you can most likely get an emulator for your PC and play it. Hope it helped :)
beat 10 grudge battles and go to your clubhouse
he is at the river
