Mega Man Battle Network 6 is the final game in the series. Based on the revisions from BN5, this game is easily the most flexible in terms of modifications allowed. You can also freely control different Navis in this game.
To follow this guide, you need VisualBoyAdvance (VBA) and a backup of the game. I do not condone piracy, but if you somehow already have a copy, follow along.
This guide will utilize the HeatMan/AquaMan freefight for the Gregar and Falzar version respectively.
Both Navis can be fought in ResearchLab 1 which is in the school.
You can download saves for this game.
Download Battle Network 6 saves.
Here is the freefight location.
Using VBA’s Memory Viewer window, the following steps will let you make temporary changes. Remember that any changes will be lost if the emulator is closed. You can make the changes permanent if the same steps are done in a hex editor such as HxD.
Choose the Battle Settings offset for your version from the list below.
Gregar BR5E US 080B0780 Falzar BR6E US 080AEF10 Gregar BR5P EU 080B0780 Falzar BR6P EU 080AEF10 Grega BR5J JP 080B2CA0 Faltzer BR6J JP 080B1430
The Battle Settings data has the following values by default:
00 64 16 00 FF 00 38 00 D7 98 41 00 16 18 0B 08
The Battle Settings format is the same as BN5 and is generally smaller and more efficient. It is documented below.
0x00 Battlefield
0x01 Unknown
0x02 Music
0x03 Battle Mode
0x04 Background
0x05 Battle Count
0x06 Panel Column Pattern
0x07 Unlock?
0x08 Battle Effects (4 bytes)
0x0C Object Setup Pointer
Remember that the Battle Settings offset from above works as a base offset from which you add the bytes on the side to get to the correct data.
0x00 Battlefield
The first byte in the format specifies the battlefield to use. You can choose from over 230 different stages. 00 is a plain stage with no special panel types.
Default is: 00
0x01 Unknown
This byte is never read and has no effect on the battle.
Default is: 00
0x02 Music
You can change the music used in battle for this byte. Any music track from the game is usable and you can even have no music. The full music list is below.
Default is: 16
00 = No Music
01 = Title Screen
02 = WWW Theme
03 = Cyber City Theme
04 = Indoors Theme
05 = School Theme
06 = Seaside Town Theme
07 = Sky Town Theme
08 = Green Town Theme
09 = Graveyard Area Theme
0A = Mr. Weather Comp Theme
0B = Event Occurrence
0C = Crisis Theme
0D = Sad Theme
0E = Hero Theme
0F = Transmission
10 = Robo Control Comp
11 = Aquarium Comp
12 = Judge Tree Comp
13 = Network Theme
14 = Undernet Theme
15 = Virus Battle
16 = Boss Battle
17 = Final Battle
18 = Pavilion Theme
19 = Winner Theme
1A = Loser Theme
1B = Game Over
1C = Boss Prelude
1D = Credits
1E = Navi Customizer Theme
1F = Winner Theme (short version)
20 = Pavilion Comp
21 = Theme of the CyberBeasts
22 = Crossover Battle Theme
23 = Shark Chase Theme
24 = ACDC Town
25 = Expo Theme
0x03 Battle Mode
This byte sets the Battle Mode which lets you play special types of battles. The full list is below.
Default is: 00
00 = Normal Battle
01 = Crossover Battle
02 = Tutorial 1
03 = Tutorial 2
04 = Tutorial 3
05 = Beast Out Tutorial
06 = Virus Battler
07 = TomahawkMan Mini Game
08 = Cross Tutorial
09 = DustMan Mini Game
0A = Hakushaku's Invincible Mode
0B = Hakushaku's Defeat
Some notes:
The Crossover Battle mode causes the battle to not load in the Japanese version. However, it loads properly in the US versions, but many features have been removed such that the custom gauge never fills and there are no other obvious effects.
For 07, when the TomahawkMan Mini Game is enabled, the player automatically becomes TomahawkMan and the custom screen is skipped. Combined with the Totem Pole enemies, you raise the gauge until all the enemies are defeated. Pushing B swings the Tomahawk for 10 damage. You should also set the value at 0x06 to 00 to get a full stage and allow flipping with L and R, which is essential.
For 09, when the DustMan Mini Game is enabled, the player automatically becomes DutsMan and the custom screen is skipped. Combined with the Flying Junk enemies, you must inhale the junk with A and smash the bombs with B. Like in the previous mini-game, a full stage will be necessary for this mini-game. This Battle Mode does not work in the Gregar version.
Battle Modes 0A and 0B have no effect in the US versions. In the Japanese versions, these perform their intended effects. For value 0A, when combined with Hakushaku, he will be invincible. On the 4th turn, Django will appear in an in-battle cutscene. For 0B, when Hakushaku is defeated, another cutscene will occur.
0x04 Background
This byte lets you change the background used during battle. The full background list is below.
Default is: FF
00 = Lan's HP BG
01 = ACDC HP BG
02 = Nothing
03 = Seaside HP BG
04 = Sky HP BG
05 = Green HP BG
06 = Robo Control Comp BG
07 = Generic Comp Green BG
08 = Generic Comp Purple BG
09 = Central Area BG
0A = Aquarium Comp BG
0B = Seaside Area BG
0C = Judgement Tree BG
0D = Green Area BG
0E = Sky Area BG
0F = Undernet BG
10 = Mr. Weather Comp BG
11 = Underground BG
12 = CyberBeast Comp BG
13 = ACDC Area BG
14 = Graveyard Area BG
15 = Mr. Weather Comp BG (storm)
0x05 Battle Count
On values greater than 00, the number of the current battle appears after the enemies appear. This is normally reserved for sequential battles.
Default is: 00
0x06 Panel Column Pattern
By default, there are 3 red columns on the left and 3 blue columns on the right. Because of Liberation battles, it is possible to have irregular column patterns. Each column can either be a 0 bit or 1 bit, red, or blue. Using this simple binary-to-hex converter, enter the column order in bits, in reverse. For example, 111000 becomes 38, the normal stage. Use the output hex value in the game. When an irregular pattern is used, you can turn your Navi around with L or R. Push both L and R to enter the custom screen.
Default is: 38
0x07 Unknown
It is unknown what this byte does.
Default is: 00
0x08 Battle Effects
This 32-bit, 4 byte value flags various effects in battle. You can add the values in hex to stack multiple effects. The list of effects are below.
Default is: D7 98 41 00
00000001 = Boss Ranking Mode
00000002 = Show Results
00000004 = Start with Max HP
00000008 = Network Battle
00000010 = Recover to Max HP After Battle
00000020 = Allow Running and Keep Full Sync
00000040 = Keep HP After Battle
00000080 = Folder is Randomized
00000100 = Allow Game Over
00000200 = Unknown
00000400 = Multiplayer Sequence Battle
00000800 = Unknown
00001000 = Unknown
00004000 = Allow Locate Enemy SubChip and Keep Full Sync
00008000 = Force Low Enemy Level
00010000 = Unknown
00020000 = Unknown
00040000 = Unknown
00080000 = Unknown
00100000 = Disallow Dark Chips
Some notes:In Boss Ranking Mode, defeating 1 enemy can still get you an S-rank. The other boss-specific rules apply.
00000008, Network Battle won’t work and forces the battle to not load.
For 00000040, this means you keep the HP you had at the end of the battle, similar to virus battles. If you ended with 1HP, you have 1HP back on the overworld.
00000400 will make the second battle vs a 100HP MegaMan. It is unknown how to customize the sequence battle.
00008000 forces lower enemy levels. If you use the Rare Virus Codebreaker code (32004804 0001), all viruses will be upgraded to their Rare form. This bit disables the code’s behavior.
0x0C Object Setup Pointer
This pointer points to where the Object Setup data is. This is data on what enemies or objects are in battle and where they appear.
Default varies by version.
After you’ve set all the Battle Settings, you can move on to the Object Setup. Use the value from above to find the Object Setup for your version.
The Object Setup format is the same, condensed format from the previous game. The format is documented below.
0x00 Object Type
0x01 X- and Y-Coordinates
0x02 Enemy Value (2 bytes)
Each “slot” takes up 4 bytes and every slot can become an enemy, the player, or an object. The game stops reading when the first byte in the format is F0 or greater. There is a limit of 4 enemies for each side, counting the player. Gregar and Falzar take up more panels and available memory, which can create unstable battles.
0x00 Object Type
This value affects directly affects how the Enemy Value functions. You can use a slot to make objects like Rocks or enemies on the red or blue side. The full object type list is below.
00 = Player-Controlled Navi
01 = Opponent Player-Controlled Navi
10 = Fight on Red Side
11 = Fight on Blue Side
20 = Mystery Data
30 = Rock
70 = Flag
80 = Rock Cube
90 = Guardian
A0 = Metal Cube
Some notes:
00 and 01 are both reserved for the Navi you normally control on the left and for multiplayer battles, the Navi your opponent controls on the right.
A value of 11 makes enemies while 10 makes allies. When you put enemies on your side, you do not share HP and enemies may behave strangely as they only normally target MegaMan and other Navis you play.
For Mystery Data to appear, the enemy value must be greater than 0D.
You can have up to 2 Rocks on the battlefield. However, you can have up to 5 Rock Cubes on the battlefield at once.
A Rock Cube can become an Ice Cube when the value at 0x02 is 03. The value at 0x03 also becomes the Rock Cube’s HP which can have a maximum of 256 HP. Ice Cubes do not take HP values.
Flags don’t normally appear in this game, but function exactly as they did since BN3. The Enemy Value becomes the Flag’s HP. Values 00-7F are HPs for your flag and 80-FF become HPs for the opponent’s flag. A flag deleted means the side the flag was on loses. The flag uses an appearing Rock Cube animation as sprite since the Flag’s original sprite was deleted.
For A0, Metal Cubes are unbreakable objects used during BlastMan’s battle. They can be removed using DustMan chips or Snowball.
0x01 X- and Y- Coordinates
Coordinates have been condensed to one value. Similar values apply just like before. Use the following values and add them to place the object on the desired panel. For example, the player normally starts on the center-left, 22, and the opponent on center right, 25.
[10]
[20]
[30]
[01][02][03][04][05][06]
0x02 Enemy Value
Enemy value is handled by 2 bytes. 00-FF handle viruses while 0100-01FF handles Navis. The first byte of the Enemy Value also functions as the Flag’s HP. The full enemy list is below.

Some notes:
The Test Virus is a 500 HP Mettaur that never attacks.
Enemies AF-B1 are the Flying Garbage enemies needed for the DustMan mini game. As DustMan, you crush or inhale the garbage. B2-B3 don’t work properly.
Enemies B5-B7 are the Totem Pole enemies needed for the TomahawkMan mini game. As TomahawkMan, you chop at the poles until they are all defeated. B5-B7 are the 3 versions used by the game but B8-BA are more difficult versions which don’t show up correctly.
Mettaurs BB-C0 are the same as the regular Mettaur except they have no name and always drop Cannon *.
Enemies C1-CC are leftover Crossover Battle enemies from BN5. The names are the same, but the versions aren’t the same anymore.
Enemy values CD-EA are leftover names from BN5’s Operation Battle. In-battle, they all appear as Mettaurs.
Enemy values 0191-019F all appear as a 4000 HP MegaMan.Values 01A0-01AB are names used to identify controllable characters and are recognized by enemies as hittable. In-battle, they all appear as a 100 HP MegaMan.
That concludes the Mega Man Battle Network 6 Custom Battle guide.
Below is a sample video demonstrating some of the possibilities allowed with this guide.
