Normally in the game's first tournament, the player has to fight GutsMan in Red Sun and AquaMan in Blue Moon on the first play. This means FireMan and NumberMan are forced to lose and their V1 cannot be fought normally. However, if the player Navi Traded with the opposite version before entering the tournament, it is possible to fight the opposite version's Navi in their V1 form. This still means that the version that traded the navi can't fight that Navi in V1. So Red Sun can't fight FireMan V1 and Blue Moon can't fight NumberMan V1. In the video, their battle was hacked into a generic area to force a battle with them.
Tournament Thumbnail Icons
The game uses two sprite archives to store the icons used in tournaments. The second archive is smaller and has these two unused icons which only read numbers. The number represents the exact number of the Navi it would have represented. These two slots could have been used by the dark Heel Navi or the pink Normal Navi.
The Normal Navi's battle sprite has one unused color. The pink color suggests that female Normal Navis were planned to be included in the game's tournaments. It would actually make more sense since the game has female operators with male Navis. There is also no tournament icon for the pink Navi, meaning it probably never made it past that stage in development.
Alternate Mystery Data Colors
This game introduced in-battle Mystery Data. If the player doesn't destroy it, they'll get a slightly better prize from a predetermined list at the end of the battle. Normally, only a green one is used and being green means its prizes are re-obtainable. Perhaps the inclusion of alternate colors suggests that the game would have had alternate prize levels where purple is the rarest. There has never been any orange-colored Mystery Data anywhere in the game and the blue color suggests it's a one-time prize. This feature was probably removed because they reduced the amount of battles that used a regular green Mystery Data and including other colors would mean more battles would need Mystery Data in them to balance it out.
Alternate Gutsman color
Gutsman has this unused alternate color, likely used to identify the SP version. MMBN4 is the only game in the series to recolor SP versions of the bosses. Gutsman already has his two alternate colors after this color, meaning this unused color could have been an earlier SP version color. Also, Gutsman is registered as the second boss, which is strange because the first boss doesn't have any unused colors.
Early ACDC Town Preview
Hidden in the game, there is an unused preview sprite for ACDC Town. Normally, the game uses one image per location, but this one was found at the end. It is presumed to be an early version of the final image because the icon does not accurately represent ACDC Town. The town in the icon suggests the park is behind Lan's house, unlike any version of the town to be known. In the final version of the town, the park is on the west and Lan's house is to the east. No palette could be found for the sprite either. Attempting to color the sprite correctly yields a more accurate preview of the sprite.
Sparkman overworld color
Sparkman's regular color exists in the game despite not actually being used. He only has this one sprite under another palette that was only used for a "hologram" before the battle with him. Sparkman never appears on the net or anywhere the color could have been used normally.
Soul Unison Karma Colors
The pictures on the left show some of the souls and their karma colors. In the game, there was distinction from dark and light. MegaMan's sprite would turn light if no dark chips were used and it would turn dark if dark chips were used. The light color is also used for Full Synchro. In the game, Soul Unison is disabled when the player is dark and even if the player is light, the light color isn't used. All the souls except Aqua and Proto Soul have karma colors, which is strange because their position on the sprite list doesn't make them the last souls, where the idea would have been scrapped. It is impossible to make these colors show up normally in the game and they all go unused.
Unused NPC Color
This NPC has an unused blue palette for its overworld sprite.
Unused Red Car
The cars in this game have the same three colors that are used in the first game. However, only yellow and blue cars can be seen driving around.
Duo and Forte Soul
At the end of the Soul list in the game, two unused souls are mentioned: Duo Soul and Forte Soul. These souls don't actually exist since there are no sprites or abilities available and the game crashes whenever they are accessed. Apparently at some point in the game, it would have been possible to obtain the soul of these enemy characters. Another oddity is that Forte Soul was not translated as Bass Soul. The concept was likely scrapped due to time constraints and Bass Cross appeared in Mega Man Battle Network 5.
Unused Gutsman attack
The name "GutsMG" can be found at the end of the attack list. Its placement is unusual but is likely that Gutsman's Machine Gun attack would have been a time freeze attack as opposed to a live attack like in the final game. It is unknown if the attack can still be executed in the game.
This game also has plenty of debug scripts which can be activated in the game. There is slightly different terminology used but the effects are similar.
Got the Entry completed Start Prelim1 Prelim1 completed You talked to the Navis in ACDC Area You talked to the Navis in Town Area Got the ____ All Mail Get Entered on the board Got the Humor Got the GunDelSl Hide Record Display Get all key items MetalMan minigame Reset lot flags Got the Subfolder Got the C-Slider Got Folder 2 Chip Set Chip Set Got the Spin items Got HP Memry Got RegUP3 Got RegUP2 Got RegUP1 Got ExpMemry Start Fire Minigame Got the DublBlue Got the DublRed Got the C-Slider parts Got 50 BattlePoints Rich Travel around the world Got the PA Delete flag set Got the NaviCust Got the items Got the Sub items Got all chips FOLD2RSBMGE
The list mentions names that aren't exactly used in the game. "DublBlue" and "DublRed" are not items or anything in the game. It is also odd that blue comes first since internally, red is first. The last entry's effect is also unknown. Perhaps it relates to a second folder which is related to the player's version.
There are also comments on the list which have no effect, but reveal developer comments.
-Hold Free Tournament. But a scenario clear flag is up, so don't continue the game. -DarkSoul appears. However, a scenario flag is up, so the scenario cannot be continued.
A character in the game is also based on Hideo Kojima, producer of the Boktai series. His character has these three lines in the debug command list.
-One day while I was on the Net, a Vampire Navi appeared in front of my Navi. It was terrifyingly powerful, but just when I thought I'd be deleted, Django came to my rescue. I'm not kidding! I have a feeling Django is fighting Vampires even as I talk. -Django and Otenko are probably on the Net right now battling evil and I'm going to join the fight as well. -That's it I'm going to write a sequel to Django, the Solar Boy.
The presence of these lines suggests that the debug command file is a sort of developer clipboard. Kojima's character has dialog in the game, but they are different from these lines. These lines suggest they would have been used in sequence after major parts in the story. Perhaps his character was going to have these lines which would have made him sound more like a game producer, than a Django fan.
In the Japanese versions of the game, 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 US and EU versions probably because either the voice is still in Japanese, or it wouldn't have fit the target audience well.
Unlike Mega Man Battle Network 3, this time the European title screens were changed in-game to feature the European logo.
