Almost 20 years ago in 2007, I played this game on the Nin­ten­do DS. While I fin­ished it, I was­n’t very good at it and was nev­er able to ful­ly com­plete the game. At the time there were no easy guides to find and had to rely on Game FAQs to do it. Fast for­ward to 2026 for the Lega­cy Col­lec­tion on Nin­ten­do Switch: I’m bet­ter at this type of game now but there’s STILL a short­age of side quest guides that are to-the-point and not lit­tered with extreme amounts of ads, so I decid­ed to put one togeth­er myself. Here you go!

Deep Space

Pulse into Vista Point’s wave por­tal, then go north and enter the new por­tal there which takes you into the Deep Space Chal­lenge. You’re going to need a few things to beat it:

• You will need have beat­en the SP forms of all the boss­es, includ­ing the option­al boss­es

Boss Locations:

• Tau­rus Fire: Echo Ridge
• Harp Note: Vista Point
• Cygnus Wing: Bore­al’s Office
• Libra Scales: Class 5‑A
• Queen Ophi­u­ca: Time Square
• Gem­i­ni Spark: Dream Island Park
• Can­cer Bub­ble: AMAKEN Foy­er
• Wolf Woods: Event Area
• Couronne XIV: City Dump

• 5 Unlock­ers (Can buy in sign comp in Echo Ridge)
• 100 stan­dard chips to get into Deep Space 2
• All 150 stan­dard chips (some of them are going to be able to be bought in Deep Space 2, so save up your Zen­ny, or dropped from virus­es there, so use the C. Find­er weapon for Mega OR you can cheat like me by using the ciphers in this LINK. Be warned that some of the mes­sage ones were made for the DS and for the Switch you just type them out. Minor spelling dif­fer­ences like “Broth­er-Bands” was just “Broth­er Bands”)
• To get to the Kelvin Transer: either delete all your Broth­er Bands, or have the Lone­ly Heart found from a hid­den pas­sage on the Liv­ing Mod­ule Comp from the space sta­tion (Liv­ing Mod­ule hid­den wave road path south­east-most jut out point). You talk to the Mr. Hertz there and answer “No”
• At the end of Deep Space 3, face your satel­lite admin as a boss to gain their Megachip. They’ll leave you with cryp­tic words: “Use it to kin­dle the 6 stars and con­quer the tru­ly lone­ly evil giant.”

The Lonely/Evil One

• So what you need to do now is to find and fight your satel­lite admin just like the oth­er boss­es, both EX and SP forms (pulse out after ex to bring out the SP form), and get BOTH CHIPS. Ex is easy, SP… not so much. Good luck. I did­n’t get even close. So I cheat­ed… with CIPHER email codes. Pega­sus Mag­ic SP: “Go On Air to trade info with friends.” Leo King­dom SP: “Star Force, the ulti­mate pow­er!” Drag­on Sky SP: “Leg­endary Mas­ter Shin”
• The “six stars” are all of the achieve­ments on the title screen (Beat the game, All stan­dard chips [150], all SP forms beat­en, all Mega Chips [30], all Giga chips [5], and defeat of your satel­lite admin), so after fin­ish­ing every­thing, save, and return to the title screen, then con­tin­ue.

• Go to Vista Point and talk to Zack. He’ll tell you there’s a strange noise com­ing from the piano. Go to the school’s gym and pulse into the piano. There’s a mas­sive group of Jam­mers there. Talk to them for a 10-round virus bust­ing chal­lenge! When you’re done, go back and talk to Zack, and he’ll ask to form a Broth­er Band with you!
• Leave Vista Point and you get an email from Leg­endary Shin that says: KMALEETZCP. Go ahead and send a CIPHER email with that code for M. Breath Mega weapon
• The only thing left is to chal­lenge Androm­e­da again because… This time it’s Androm­e­da INFINITY!! 4000HP and very fast attacks.
• When you defeat it, you’ve ful­ly com­plet­ed the game!
