Noise Change

Noise Change is the main transformation system of Mega Man Star Force 3. MegaMan will receive his first Noise Change in Chapter 4.

How to Obtain

G virus battle

The first step in getting a Noise Change is getting into a WARNING battle with G viruses. Whenever you get a random virus encounter that doesn't have a boss in it, there's a 1-in-14 chance that the viruses will all be upgraded to G size and the battle will have a WARNING on the bottom screen before it begins.

You will want to have both SearchEye and Cloaker OFF for this, as a SearchEyed battle will never have G viruses, and Cloaker increases the V3 boss encounter rate as well as reducing the regular virus encounter rate. Neither of these are things you want when going for a Noise Change. Yes, having Cloaker active makes you much less likely to get a G virus battle, rather than increasing the chance as you might think.

For best results you will probably also want to be in a Cyber Core where bosses don't appear.

Triggering Noise Change

Once you've deleted the G viruses, you have a change to get a Noise Chance. Yep, it's not guaranteed. The chance to get a Noise Change starts at 33% (not 1/3) and increases every time you don't get it; first to 50%, then to 70%, then to 80% and finally to 100%. Once you get the Noise Change, it resets back to 33%.

If you're looking for a specific Noise you will want to save the game every time that deleting the G viruses doesn't trigger a Noise Change, and reset the game when it does trigger a Noise Change but you don't get the Noise you wanted. This will keep the Noise Change trigger % up.

JP version only: If the Transformation Archive is active, then Noise Change will never trigger. You can have Transformation Archive data stored, just make sure that the red folder isn't equipped. Noise Change trigger % does not change while Transformation Archive is active.

When you pass the Noise Change check, the game will perform a series of subsequent checks, first to see if you'll get Rogue Noise, then to see if you'll get a Noise from the opposite version, and finally what Noise you get.

First two Noise Changes

If this is your first or second Noise Change (included the one forced on you during the story), then the game will skip the Rogue Noise check and opposite version check described below. This means that you cannot get Rogue Noise or an opposite version Noise until at least your third Noise Change.

Also, if you reject your second Noise Change, then it doesn't count! You will have to accept your second Noise Change before you have a shot at getting one of those rarer Noises.

Rogue Noise check

In determining which Noise you get, first the game will check if you're eligible for Rogue Noise, which is when you don't have any Real Brothers. This is a 10% check and increases by 10% every time you miss it. It resets when you get Rogue Noise or if you get a new Noise Change while having Real Brothers.

The Rogue Noise chance does not increase during your first two Noise Changes even if you meet its requirements at that time, meaning it will always start at 10% from your third Noise Change onwards.

If you pass the Rogue Noise check, then you just get Rogue Noise and all the other checks are skipped. If you miss it, then the game continues to...

Opposite version check

This is a 12.5% check, if you pass it then you'll get a random Noise from the other game version (e.g. get a Red Joker Noise when you're playing Black Ace). Otherwise, you will get a random Noise from your own version.

Version Noise Once the game has determined which version you will get a Noise from, there's a 20% chance to get each of the 5 Noises of that version. If you're already in a Noise from that version, then the game will exclude it, and instead you have a 25% chance to get each of the 4 other Noises of that version.
