Completion bonuses:
To unlock Arcade Mode, First Person View, Parts Index, and The Grand Battle in
Single, and Versus Mode CPUs, you must complete "A New Journey" mode in single
player.
Link bonuses:
Use a Game Boy Advance link cable to connect to Custom Robo GX to unlock the
Dark Core stage and new Robo parts in the Japanese version of the games.
First person view:
Defeat Rahu 3 at the end of the game to unlock first person view. You can keep
this off, however turning it on does not automatically make you see in first
person view. When you get into battle with this option on, you can switch
in-between the two views by pressing C-stick Up or switch back to third-person
view by pressing C-stick Down.
Alternate stage:
Select versus mode, then highlight Basic Arena or No Man's Land and press Z to
change their appearance.

Select versus mode then choose three matches. Finish the three matches and a
new stage will be unlocked.
Dark Star versus mode stage:
Play versus mode 50 times with any one Robo. For example, play vs. mode 50
times with Ray01.
Versus battle CPUs:
Successfully complete the game in story mode.
Athena:
After completing the Bronze Handicap Match and getting all the silver trophies,
not including the bronze handicap match, you will be able to compete in the
Silver Battle Royal. You will not get any new parts for any of the matches
except for the last one. Once you finish the last battle, you will get the
Athena body part (illegal).
Cans:
To get "Can Robo" Can Bomb, Can Pods, Can Boots, and Can Gun, win the
Tournament in your house. You can now enter Lucy's room. In there you will see
lots of people talking about what they did for the game (similar to "talking"
credits). Go through the second door and you will see more people. In the
second room there is a robot (not a Custom Robo). Talk to him after he is done
talking. The game will save. Go to the nearest parts generator and get ready to
laugh at what you just unlocked.
Chickenheart:
In the Z Boss battle, look on the north side of the west pillar.
Crystal Strike:
Defeat the fourth CPU in in the Test Center, then keep talking to it until you
get the Crystal Strike gun.
Rakansen:
Win all the Amusement Park Tournaments with bronze trophies.
Ray Legend Robo:
Win all the cups in the Z Headquarters tournaments with a gold trophy, then
talk to Oboro.
In Grand Battle (Episode 2), after winning every tournament in the city you
will have access to the Outer World. When there, go to the Z Museum and defeat
everyone to be able to go to the Z Boss Room. Once there, get a gold trophy to
get the Ray Legend.
When you get to the Z boss room, you will fight (in order), Shiner, Eliza,
Izabella, Oboro, then your host, Sensei. Sensei will then introduce your sixth
opponent (the special guest), who is a simulation of Hero's father, the first
leader and founder of the Z syndicate. He will say that his Robo is obsolete,
and the Robo he is using is actually the Ray Legend Robo. It has a much
stronger attack and much weaker defense than Ray 01, and will be easy to defeat
if you can avoid him and knock him down. Try using all of Rahu 1 but replace
his gun with the vertical gun.
Ray Warrior:
Win all the cups in the Amusement Park tournaments with a gold trophy, then
talk to the policeman at the front gate.
Rahu parts:
To get the first set of parts, go to the Z Headquarters, talk to Oboro, and
select Eliza's Mansion. Go in between the glass and the wall, go all the way
to the left, then up, then right. You will be in the glass case. Press A to
find Rahu 1's parts and the Rahu 1 chip.
Do the Bronze handicap match. When Lucy appears to fight, talk to her until
you get Rahu 2's parts.
To get Rahu 3's parts, go the Amusement Park. Do the Silver free for all
battle. Go down and into the carriage near the merry-go-round. Press A to
find Rahu 3's parts.
Wave Laser:
Go to the Lab Handicap battle, then press A against the books. You will get
the Wave Laser gun illegal part.
X Laser:
When you first enter Bogey's, look behind the counter facing the wall.
To find the X Laser (illegal part), in a Grand Battle mode, go to Bogey's Café.
Walk behind the counter and select the shelf. You will now have an illegal part.
