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. 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.[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.

Menu Avoiding Encounters 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.

Dimming on Mine collision
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.
In later versions, Mine will only hit damage the enemy once.

AntiRecovery Cut In lock
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 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 A.

DarkChip JunkSoul oversight
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 early versions 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 selected Folder when New Game+ is started.
New Game+ Regular Chip glitch
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.

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 Mod Cards in their save file.

Visual errors
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.

Evil Chip Cut In glitch
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.

Panel Reserve glitches
BoyBomb Reserve glitch
If a BoyBomb chip obstacle is on the field and is pushed back and forth (using attacks such as AirShot) until it runs out of HP and destroyed, the panel it was on will still be occupied, even though it is empty. MegaMan will be unable to walk on to that panel for the rest of the battle.

Dark Double Soul Off Field glitch
In Network Duel, this requires an Evil MegaMan being Player 2 on the Link Cable. Evil MegaMan needs to be hit by an attack that knocks back (i.e. GrabBanish) and while in the slide, gets deleted by an attack or HP drain (i.e. LaserMan or Poison panel) to trigger Dark Double Soul. Dark Soul will keep on sliding and go off screen. There is no way to hit the Evil MegaMan player. The Dark Soul will eventually return back to the battlefield.
