=== WoodMan scenario slowdown ===
=== WoodMan scenario slowdown ===
During WoodMan's scenario in the second tournament of the game, the player must navigate Park Area in order to reach WoodMan, who is in [[Park Area 3]], while Wood Towers are extruding from the path. If the player enters a menu or battle in this area, the game will slow to a halt upon returning to the map if the game is played on an original Nintendo DS. It does not occur on other hardware such as original GBA, Nintendo DS Lite, Game Boy Player and Wii U. If the game is left running for a while, it will eventually return to full speed again. This glitch exists in every cartridge version of the game, and is one of the few Nintendo DS compatibility problems officially acknowledged by Nintendo.<ref>[https://www.nintendo.com/consumer/systems/gameboy/trouble_specificgame.jsp#megaman Nintendo on the WoodMan glitch]</ref>

There are some ways of circumventing this glitch:
* Playing the game on a Game Boy Advance, Game Boy Advance SP, Game Boy Micro, Game Boy Player or Nintendo DS Lite.
* Playing the game on any system other than the original Nintendo DS.

On a technical level, the glitch occurs when one of the Wood Towers in Park Area is on its last frame of animation when the map screen is reloaded. Upon reloading the map, the game erroneously does not check whether the animation frame index needs to be reset, and as a result, attempts to load a non-existent sprite from an invalid memory address. The junk data read differs between GBA/NDS hardware revisions <ref>http://problemkaputt.de/gbatek.htm#gbaunpredictablethings</ref>; on the original Nintendo DS the junk data is interpreted as continuous sprite data, causing the game to hang until it eventually wraps around back to mapped memory, whereas on other hardware revisions, the junk data is interpreted as the end of the sprite, nullifying the effect of the glitch.

In the NaviCustomizer, putting in more than 4 different colors of programs is supposed to give you several bugs in battle. However, if you save a NaviCustomizer setup that has more than 4 colors, remove programs until you have 4 or less colors, then cancel saving and exit the NaviCustomizer, you keep your last saved configuration but any color bugs will be removed. This also works the other way around, by adding programs until you have more than 4 different colors, then cancel and exit the NaviCustomizer, you keep your last configuration but also have a color bug.

===Menu Avoiding Encounters glitch===
===Encounter Reset Menu glitch===
While playing as MegaMan on the Field Screen, whenever the menu is opened and entered (such as Folder and Save), the encounter rate is reset. As such, it’s possible to completely avoid encounters by opening and closing the menu every few seconds.
While playing as MegaMan on the Field Screen, whenever the menu is opened and entered (such as into Chipfolder or Save), the encounter rate is reset. As such, it’s possible to completely avoid encounters by opening and closing the menu every couple of steps.

===AntiRecovery Cut In crash===
===AntiRecovery Cut In lock===
If you have an Anti Recovery chip trap active and the opponent attempts a [[Screen Dimming Cut In|Cut In]] with a dimming recovery chip (for example, Roll), then you cut in another trap chip; the battle will freeze.
{{nw|Add details how Legacy Collection fixes it.}}
If you have an AntiRecovery chip ???? trap on, then attempt to set up another AntiRecovery chip, if the opponent attempts a [[Screen Dimming Cut In|cut in]] with a dimming recovery chip (for example, Roll), the battle will soft-lock. The game will require a reset.


In the English version, the chip will bypass the Anti Recovery trap and continue its effect.

=== Slasher AntiDamage oversight===
=== Slasher AntiDamage oversight===
If you hold A to activate Slasher and an AntiDamage trap is active, you will be immune to all non-piercing attacks. Your Double Soul will also not dissipate after 3 turns. This effect ends once you let go of A.
If you hold A button for Slasher and an AntiDamage ???? trap is active, you will be immune to all non-HP draining attacks until Slasher is triggered by an an enemy entering your area. As many enemies don’t infiltrate your field, you’re essentially invincible for the rest of the battle. Your Double Soul will also not dissipate after 3 turns. This effect ends once you let go of the A button.
 
In later versions, the AntiDamage triggers immediately, even if Slasher is active.

== Minor glitches ==
===New Game+ Folder glitches===
In the earliest version of MMBN4, when a New Game+ is started, the Folder selection is reset into Folder1. This creates some impossible Folder set-ups. These glitches can be used together.
 
In later versions, the game will remain the currently equipped Folder when New Game+ is started.
 
====New Game+ Regular Chip glitch====
[[File:MMBN4-NewGame-Regular-glitch.png|right]]
Equip Folder2 and move the Regular Chip to the 1st slot. In Folder1, move the chip you want to be Regular to the 1st slot (this chip can exceed the current MB limit). Once the next Continue is started, Folder1 will be equipped and that 1st chip slot in the Folder will be your Regular Chip. If at any time you edit the Folder and exit successfully, the 1st slot chip will no longer be the Regular Chip.

=== Dimming on Mine collision ===
====New Game+ Exceed Limit oversight====
Use a dimming chip the moment an enemy lands on the panel with Mine and the Mine will damage the enemy multiple times during dimming. In later versions, this will only damage the enemy once. The Repair chip can be used to spot the Mine more easily.
Add MegaFolders or GigaFolders on MegaMan, then fill Folder1 to the exceeded limits. Afterwards, unequip the abilities and equip any other Folder. Once the next Continue is started, Folder1 will be equipped despite MegaMan no longer able to equip it properly. The Folder can still be edited and it will let you exit it normally. If you go into the MegaMan menu at any time, Folder1 will be automatically unequipped.

===Permanent Evil progress lock===
If MegaMan's karma is in [[Karma#Permanent_Evil|permanent Evil]], the door from Black Earth 1 to Black Earth 2 has yet to be opened, and the ShadeMan chip has not be registered in the Library, you will be unable to progress to Black Earth 2. The door requires all V1 Navi Chips including ShadeMan, and the only way to get it requires beating ShadManΩ in non-Evil emotion, which cannot be achieved if Mega Man is permanent Evil. Also the chip is not in any Chip Traders, limiting the access to only that battle.
To get out of this situation, the player must obtain the ShadeMan chip by linking with another player, either trading the chip or compare Libraries.

=== Pop-Up Overlap collision ===
===Folder Edit lock===
Use Pop-Up when an enemy is directly on top of you. You will be continuously hit for a massive amount of damage.
In the Folder Edit, if you attempt to put in a chip over your folder limit (e.g. more than 4 Standard chips) via pressing A button twice or swapping in a chip, and press left or right to the other screen at roughly the same time, the game will soft lock during the screen sliding animation.

=== Visual errors===
These are visual errors in the game that can be seen without taking special steps to make it happen.
====GutsMan colors====
GutsMan's darker red on his body is the same color as the lighter red, making them blend together. This error is only for the original GutsMan sprite, as his SP and DS color swaps have separate colors for the darker and lighter shades.

=== Double Soul Icon visual ===
====BassXX's movement====
If you select a full set of 5 chips in the Custom Screen then perform a Double Soul with your 5th chip, all the un-selected icons will light up again. However, they cannot be selected.
Whenever BassXX moves, his afterimages appear bright yellow instead of purple. This is because the wrong palette is being used specifically for Bass's XX version.

=== Backwards Cape Bass glitch ===
====BugFix Positioning quirk====
If Bass is countered while doing his back Dark Arm Blade, he will return to position stunned with his cape backwards. This remains this way until Bass performs Dark Arm Blade again.
While a Navi is using the BugFix chip, their sprite's shadow is slightly moved up during the animation. The positioning fixes itself after the animation.

{{nw|Does this happen in other areas?}}
{{nw|Check SparkManα as well}}
After deleting Roll's ghost data in Town Area 3, equipping Fish sometimes causes you to encounter battles with Fire viruses (and no Aqua viruses). Also, OilBody will always choose the same encounter (with two VolGears, VulGears or ValGears).
The location of the SparkManβ ghost encounter on the net is in ACDC Area 3, but the background will be using the one for Town Area instead of ACDC Area.

===BattleChip Pack Order===
In the English language version of the game, a few chips are placed in unconventional spots when the Pack is ordered in ABCD order. This is due to all the games having the ABCD sorting index being done for each chip manually (e.g. MMBN3’s Recov10, Recov120, Recover150 order VS MMBN4’s Recov10, Recov30, Recov50 order).
*CrackOut being placed with chips starting with K.
*ShotStar being placed with chips starting with M.
*DrkLine is placed above DblPoint.
In the Legacy Collection, they are now sorted in their correct ABCD order.

=== Save Retry Failure glitch===
====DarkVulcan MegaChip quirk====
In the initial Japanese release of Rockman EXE 4, if the game fails to save for whatever reason and the player selects 'yes' to retry, the game will crash. This is caused by a wrong jump target script in the save retry menu script. In all subsequent releases, this glitch is fixed and the game will properly retry the save if the player selects 'yes'.
DarkVulcan can be taken away by the Beat NCP even though it is not a Mega or Giga Chip. This classification was likely due to DarkVulcan being pooled with MegaChip limitations for the Dark Soul AI, the other DarkChips are pooled with Standard Chips.


Note: the game may not crash and instead display incorrect text if the player has Mod Cards in their save file.
In later versions, DarkVulcan won’t be taken.

DarkVulcan can be taken away by the Beat NCP even though it is not a Mega or Giga Chip. In later versions, it won’t be taken.
[[File:MMBN4-ShadeManDS-S.png|right]]
If MegaMan ends a battle in Evil emotion, the reward from Navis will be their DS Navi chips. If ShadeManSP is defeated in this way, he will drop the ShadeManDS S chip instead of the correct chip name, ShadeManDS X. As the S code chip doesn't exist, it will not appear in the Pack. In later versions, the correct chip code is given.

However, it then turns the chip into FireMan (will trigger AntiNavi, command code works) and deals damage based on the chip you used.

If the Roll chip is used with a x2 multiplier (like from Full Synchro and Angry emotions), MegaMan will heal to his maximum HP instead of how much damage Roll would deal.
In later versions, Roll will only heal how much damage she would have dealt as intended.
In the Legacy Collection, this fix is applied, but if Roll is used against an AntiRecv trap, it will drain all of the player’s HP instead of the damage Roll would’ve dealt.

FireMan’s FireCircle attack is supposed to have ([[Bosses_in_Mega_Man_Battle_Network_4#DS_Navis|DSLV]] x 30) attack power, but only stores the low 8 bits so the AP is lower than it should be. For example: 300 AP (0x12C) becomes 44 AP (0x2C).
This results in an attack power of 14 (should be 270) for DSLV 9, and an attack power of 44 (should be 300) for DSLV 10. DSLV 1~8 are not affected.

The LaserMan and PrixPower BattleChip's Power Down Laser attack actually travels 6 panels down the row. However, it doesn't check bounds so it wraps around to the next row, hitting panels with an invisible hitbox.

When a non-flashing attack attacks that panel, it was freed and the panel still thinks it has its collision data on it. When Bass goes back on that panel creating another object causes him to get hit by it every frame.

===Waiting Room Navi Tournament glitch===
In Legacy Collection, you can manually choose where to save a received Navi in the Waiting Room. At the start of a story tournament, when deciding the tournament bracket, the game will scan the Waiting Room left to right, top to bottom for opposite version Navis. However, it will stop when a slot is encountered that has never been used before. As a result, a Navi in the Waiting Room may not show up in story tournaments if there are any never-used slots before that Navi's slot.
In the GBA version, the Navi will appear in the story tournament even if there's never-used slots before it.

This page is a list of glitches that appear in Mega Man Battle Network 4.

Major glitches

WoodMan scenario slowdown

During WoodMan's scenario in the second tournament of the game, the player must navigate Park Area in order to reach WoodMan, who is in Park Area 3, while Wood Towers are extruding from the path. If the player enters a menu or battle in this area, the game will slow to a halt upon returning to the map if the game is played on an original Nintendo DS. It does not occur on other hardware such as original GBA, Nintendo DS Lite, Game Boy Player, and Wii U, as well as the Wii U Virtual Console version of the game. It also does not occur in the Legacy Collection version of the game.

If the game is left running for a while, it will eventually return to full speed again.

This glitch exists in every version of the Game Pak, and is one of the few Nintendo DS compatibility problems officially acknowledged by Nintendo.[1]

There are some ways of circumventing this glitch:

  • Playing the game on any system other than the original Nintendo DS.
  • Equipping SneakRun before entering Park Area 1 while having high enough base HP to escape all battles in the area:
    • 251 HP or more in the first playthrough;
    • 551 HP or more in the second playthrough;
    • 851 HP or more in all subsequent playthroughs.
  • Only on Red Sun version: deleting WoodMan's entry from the Waiting Room Reception in the Network menu before inspecting the matchups for the first round of the Eagle Tournament of that playthrough.

On a technical level, the glitch occurs when one of the Wood Towers in Park Area is on its last frame of animation when the map screen is reloaded. Upon reloading the map, the game erroneously does not check whether the animation frame index needs to be reset, and as a result, attempts to load a non-existent sprite from an invalid memory address. The junk data read differs between GBA/NDS hardware revisions [2]; on the original Nintendo DS the junk data is interpreted as continuous sprite data, causing the game to hang until it eventually wraps around back to mapped memory, whereas on other hardware revisions, the junk data is interpreted as the end of the sprite, nullifying the effect of the glitch.

Color Bug Nullification glitch

In the NaviCustomizer, putting in more than 4 different colors of programs is supposed to give you several bugs in battle. However, if you save a NaviCustomizer setup that has more than 4 colors, remove programs until you have 4 or less colors, then cancel saving and exit the NaviCustomizer, you keep your last saved configuration but any color bugs will be removed. This also works the other way around, by adding programs until you have more than 4 different colors, then cancel and exit the NaviCustomizer, you keep your last configuration but also have a color bug.

If you have an AntiRecovery chip ???? trap on, then attempt to set up another AntiRecovery chip, if the opponent attempts a cut in with a dimming recovery chip (for example, Roll), the battle will soft-lock. The game will require a reset.

In the English version, the recovery chip will bypass the AntiRecovery trap and use its effect.

Slasher AntiDamage oversight

If you hold A button for Slasher and an AntiDamage ???? trap is active, you will be immune to all non-HP draining attacks until Slasher is triggered by an an enemy entering your area. As many enemies don’t infiltrate your field, you’re essentially invincible for the rest of the battle. Your Double Soul will also not dissipate after 3 turns. This effect ends once you let go of the A button.

In later versions, the AntiDamage triggers immediately, even if Slasher is active.

DarkChip JunkSoul oversight

MMBN4-DarkChip-JunkSoul.png

Since selected but not used chips still appear in Junk Soul’s Junk-Chip mechanic; If Dark Chips are selected and not used, then MegaMan restores himself from the Worried emotion into Junk Soul, they will appear again through Junk Soul’s recycle. MegaMan can use those Dark Chips without the consequence of going Evil emotion or losing 1 HP permanently.

New Game+ Folder glitches

In the earliest version of MMBN4, when a New Game+ is started, the Folder selection is reset into Folder1. This creates some impossible Folder set-ups. These glitches can be used together.

In later versions, the game will remain the currently equipped Folder when New Game+ is started.

New Game+ Regular Chip glitch

MMBN4-NewGame-Regular-glitch.png

Equip Folder2 and move the Regular Chip to the 1st slot. In Folder1, move the chip you want to be Regular to the 1st slot (this chip can exceed the current MB limit). Once the next Continue is started, Folder1 will be equipped and that 1st chip slot in the Folder will be your Regular Chip. If at any time you edit the Folder and exit successfully, the 1st slot chip will no longer be the Regular Chip.

New Game+ Exceed Limit oversight

Add MegaFolders or GigaFolders on MegaMan, then fill Folder1 to the exceeded limits. Afterwards, unequip the abilities and equip any other Folder. Once the next Continue is started, Folder1 will be equipped despite MegaMan no longer able to equip it properly. The Folder can still be edited and it will let you exit it normally. If you go into the MegaMan menu at any time, Folder1 will be automatically unequipped.

Permanent Evil progress lock

If MegaMan's karma is in permanent Evil, the door from Black Earth 1 to Black Earth 2 has yet to be opened, and the ShadeMan chip has not be registered in the Library, you will be unable to progress to Black Earth 2. The door requires all V1 Navi Chips including ShadeMan, and the only way to get it requires beating ShadManΩ in non-Evil emotion, which cannot be achieved if Mega Man is permanent Evil. Also the chip is not in any Chip Traders, limiting the access to only that battle.

To get out of this situation, the player must obtain the ShadeMan chip by linking with another player, either trading the chip or compare Libraries.

Minor glitches

Visual errors

These are visual errors in the game that can be seen without taking special steps to make it happen.

GutsMan colors

GutsMan's darker red on his body is the same color as the lighter red, making them blend together. This error is only for the original GutsMan sprite, as his SP and DS color swaps have separate colors for the darker and lighter shades.

BattleChip Pack Order

In the English language version of the game, a few chips are placed in unconventional spots when the Pack is ordered in ABCD order. This is due to all the games having the ABCD sorting index being done for each chip manually (e.g. MMBN3’s Recov10, Recov120, Recover150 order VS MMBN4’s Recov10, Recov30, Recov50 order).

  • CrackOut being placed with chips starting with K.
  • ShotStar being placed with chips starting with M.
  • DrkLine is placed above DblPoint.

In the Legacy Collection, they are now sorted in their correct ABCD order.

Save Retry Failure glitch

In the initial Japanese release of Rockman EXE 4, if the game fails to save for whatever reason and the player selects 'yes' to retry, the game will crash. This is caused by a wrong jump target script in the save retry menu script. In all subsequent releases, this glitch is fixed and the game will properly retry the save if the player selects 'yes'.

Note: the game may not crash and instead display incorrect text if the player has Patch Cards in their save file.

Occurs only if MegaMan's karma is from 470 to 479. In a Network Duel, the game will allow you to use a screen-dimming Evil chip in a cut in, when it usually should not. However, it then turns the chip into FireMan (will trigger AntiNavi, command code works) and deals damage based on the chip you used.

Research VS AntiRecv in English GBA. Check if max AntiRecovery is fixed in MMBNLC July 2023 update.

If the Roll chip is used with a x2 multiplier (like from Full Synchro and Angry emotions), MegaMan will heal to his maximum HP instead of how much damage Roll would deal.

In later versions, Roll will only heal how much damage she would have dealt as intended.

In the Legacy Collection, this fix is applied, but if Roll is used against an AntiRecv trap, it will drain all of the player’s HP instead of the damage Roll would’ve dealt.

Double Soul Off Field glitch

In Network Duel, this can only occur to Player 2 on the Link Cable. MegaMan needs to be hit by an attack that knocks back (e.g. GrabBanish, WindRacket) and while in the slide, open the Custom Screen. If Player 2 performs Double Soul during that turn, when they return, MegaMan will keep on sliding and go off screen. There is no way to hit the MegaMan.

HeatChaser Breaking glitch

If BurnMan's Heat Chaser is destroyed with a breaking attack, it will spawn a new hitbox on the field and can hit MegaMan seemingly through nothingness. This is due Heat Chaser hitboxes referencing the wrong parent object if you destroy the Heat Chaser as it's firing, it will then spawn a new hitbox through a different attack (e.g. MiniBomb).

FireManDS FireCircle error

FireMan’s FireCircle attack is supposed to have (DSLV x 30) attack power, but only stores the low 8 bits so the AP is lower than it should be. For example: 300 AP (0x12C) becomes 44 AP (0x2C).

This results in an attack power of 14 (should be 270) for DSLV 9, and an attack power of 44 (should be 300) for DSLV 10. DSLV 1~8 are not affected.

Power Down Laser Range

Check if the boss does this too. Check if other chips have this behavior.

The LaserMan and PrixPower BattleChip's Power Down Laser attack actually travels 6 panels down the row. However, it doesn't check bounds so it wraps around to the next row, hitting panels with an invisible hitbox.

Since there is out of bounds panels to the left and right to the battlefield, the panel travel count is reduced by 2 before it wraps around to the next row.

Bass Collision glitch

When Bass uses Helz Rolling, he stores a reference to the orb sprite object. After the attack, he frees the object but doesn't clear the reference. When he fails to use Dark Arm Blade because there's no open panels next to the player, he frees whatever he has a reference to. When a non-flashing attack attacks that panel, it was freed and the panel still thinks it has its collision data on it. When Bass goes back on that panel creating another object causes him to get hit by it every frame.

If the MagTect is knocked back by an attack during a frame where its timer is divisible by 4, it will be pushed off the battlefield. It can no longer be damaged, but will be considered as deleted after a few seconds pass.

Waiting Room Navi Tournament glitch

In Legacy Collection, you can manually choose where to save a received Navi in the Waiting Room. At the start of a story tournament, when deciding the tournament bracket, the game will scan the Waiting Room left to right, top to bottom for opposite version Navis. However, it will stop when a slot is encountered that has never been used before. As a result, a Navi in the Waiting Room may not show up in story tournaments if there are any never-used slots before that Navi's slot.

In the GBA version, the Navi will appear in the story tournament even if there's never-used slots before it.
