Mega Man Battle Network 4/Regional Differences

This is a sub-page of Mega Man Battle Network 4.

To do: A lot more region-exclusive bugs.

Battle Network 4 is already known for being a buggy mess, but the Japanese versions are even worse!

Japan 1.0 -> Japan 1.1

Two Japanese versions were released, with v1.0 being compiled on November 11, 2003, and v1.1 being compiled on January 27, 2004. As a result, v1.0 is even more unstable than the others.

• Equipping 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.
• 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.
• Attempting to save after a previous save attempt failed will corrupt the save file thanks to an incorrect branch. Interestingly, attempting to do this with any ModCards installed will just corrupt the text, but not the save.
• While playing the WindMan scenario in Park Area, if positioned just right, MegaMan can talk to the tornados flying through the area. Each area has their own effects involving a talkable object that existed in that area in other scenarios, and MegaMan can keep walking while the textbox is open. Also, while the textbox is open, MegaMan will not get any encounters.
  • Park Area 1: Opens the Park Area 1 SubChip Dealer Menu. Once exited, all tornadoes in the area will disappear.
  • Park Area 2: A Mr. Prog dialogue.
  • Park Area 3: Obtain a Video1 KeyItem from VideoMan's scenario.
• If MegaMan has Evil karma, defeating ShadeManSP will reward him with ShadeManDS S, rather than ShadeManDS X. Since the former isn't a valid Chip code, it will not appear in the pack, making it impossible to use.
• During the game's finale where Regal falls down and the game slows down, if the rest of the cutscene is skipped via pressing Select, the credits will play slowed down.
• In early versions, if PoisonPharaoh is affecting ShadeMan, he won't turn into his bats when attacked and can be damaged normally. In the later versions, ShadeMan will still turn into bats if he's affected by PoisonPharaoh.

Japan 1.1 -> International

Otenko's Voice

In the Japanese versions, during the Crossover cutscene where Django and Otenko encounter ShadeMan, this voice clip would play as they defeat ShadeMan. This voice clip was removed in the US and European versions probably because either the voice is still in Japanese, or it wouldn't have fit the target audience well.

Regional Logos

Japan	US	Europe

Unlike Battle Network 3, this time the European title screens were changed in-game to feature the European logo.

Environmental Text Changes

The game contains some changes to environmental texts, mainly translations, but the takoyaki stand (and the poster promoting it) was changed into a hot dog stand in the international versions.

Japan	International

Extra Code

The English version included an additional code for Mega Man Battle Chip Challenge which will unlock the HubStyle Navi Chip when entered.

e-Reader Content

Due to the lack of popularity regarding the e-Reader outside of Japan, all of the content that was made for it is inaccessible in the international versions. Despite this, it is still possible to hack in the effects in the international game, including the Duo chip and the BassXX boss fight.

Strangely, although the hardware was never released outside of Japan, the Battle Chip Gate content is fully functional and is enabled the same as the Japanese game.

Bug Fixes

The international version fixed a few more bugs that the Japanese version had:

• Using a dimming chip on the exact frame an enemy lands on a mine will cause that enemy to not trigger their invulnerability frames fast enough, thus allowing extra damage.
• If the player holds A to activate Slasher while an Anti-Damage trap is active, the player will be completely immune to non-piercing attacks, and allows them to maintain their Double Soul. The bug fixes itself once A is let go.
  • Similarly, if you hold A button for GunDelSol and an AntiDamage ???? trap is active, the AntiDamage will trigger and MegaMan will return but GunDelSol's visual will still play unattached to his arm. GunDelSol will be active but won't drain enemy HP. If MegaMan uses a non-dimming chip or gets hit, GunDelSol will disappear.
• In the Japanese version, opening a sub menu will reset the step counter. The reason for this is because the sub menu also causes a brief map reset, however the Japanese game never reserves the step counter during it.
• 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.
• DarkVulcan can be taken away by the Beat NCP in the Japanese version even though it is not a Mega or Giga Chip. In later versions, it won’t be taken.
• If you have to have maxed out Emotion Value and you land a Counter Hit with an attack that would have dealt Emotion Value damage into Full Synchro, the next Mod Card attack will be multiplied by 1.5×. If it was a multi-hit that countered, the next hit from it will be multiplied by 1.5×.
• If the Roll chip is used with a ×2 multiplier (like from Full Synchro and Angry emotions), MegaMan will heal to his maximum HP instead of how much damage Roll would deal.
• This works with any Chip Trader. Put in the chips, then press L repeatedly when selecting Yes for confirmation. If successful, the textbox text sound will play as the screen is stuck on complete blackness. Pressing A or B will end the black screen and continue the Chip Trader process.
• If the Custom Screen is opened while the Counter Hit text is on screen, it will have the opponent ???? Trap indicator shown until the next turn. The ???? text will be in wrong colors in this time.

Europe -> North America

The European version, being made a few days before the North American release, has a few translation errors that were fixed (not nearly enough to make the translation good, mind you).

Europe	North America
Want to saver you progress?	Want to save your progress?

A typo in the save screen was fixed, although it still appears in the American manual.

Europe	North America
SingleBatle TripleBatle	SinglBattle TriplBattle

The mulitplayer battle options use different spelling depending on the region.

Europe	North America
Transmission stopped. Try?	Transmission stopped. Try again?

This sentence was left incomplete in the European translation; due to text space limitations, the North American version adds an additional text box.
