Missable content
From The Rockman EXE Zone Wiki
This page lists items and content in the series which can be permanently missed, or become substantially more difficult to obtain, if not obtained by a certain point in the game.
Note: due to the Chip Trader's low odds of getting the chip you need, chips which can otherwise only be obtained through the Chip Trader are also treated as missable on this page.
Some items have been bolded, these are noteworthy due to not having an infinite alternative source for that code or the * code.
Mega Man Battle Network 1
These also apply to Rockman EXE Operate Shooting Star.

Green Mystery Data
The contents of green Mystery Data vary for each difficulty. In some cases, depending on the difficulty and version of the game, green Mystery Data is the only (infinite) source of a chip code (aside from the Chip Trader).
For the chips listed below, once the player has moved on to the next difficulty, they can no longer obtain (infinite) copies of that chip, other than:
- Chip Trader
- Shop with limited stock
- Chip Order using a finite source of another code
- Version-specific virus drop

Viruses
For most viruses, lower versions can be encountered even on the highest difficulty (Continue 3+). However, there are a few viruses that only appear on a specific difficulty. As a result, this may lock you out of obtaining certain chip codes, which can otherwise only be obtained (very rarely) from the Chip Trader.
| Difficulty | Virus | Missable chip codes | Alternative ways to get |
|---|---|---|---|
| Game 1 only | GaiaEX | - | All codes can be obtained from Gaia and Chip Order |
| CirKill | - | All codes can be obtained from CirKillEX | |

WaterGod Comp Gold Mr. Prog
The WaterGod Comp can only be accessed if Lan fights Paulie as an opponent in the Red Sun / Blue Moon Tournament. In the WaterGod Comp, a gold Mr. Prog known as the WaterGod Program has a low chance to spawn upon jacking in to the comp. It will give up to 5 rewards from a pool of 8, depending on the current difficulty. As such, certain BattleChip rewards for Game 1 and/or 2 can be missed.
Whether Paulie will appear in the Red Sun / Blue Moon Tournament, and which rewards will be given by the WaterGod Program, are both determined at the start of the game. Therefore, the player has no control over this and getting the chips below is simply up to luck.
| Difficulty | Missable chip | Alternative ways to get |
|---|---|---|
| Game 1 only | WideBlde C | Elec Tower Comp 2 BMD (2nd time), Chip Trader |
| Lance A | Chip Trader | |
| Game 2 only | Geddon2 Y | Chip Trader |
| Barr200 I | Chip Trader | |
| MegEnBom W | Chip Trader | |
| VarSwrd J | Chip Trader |
Blue/Purple Mystery Data
None of the blue Mystery Data and purple Mystery Data in the game are missable. If a BMD/PMD is not collected in a certain playthrough, the contents will carry over to the next playthrough. Once a BMD/PMD has been collected, it will reappear in the next playthrough with its contents upgraded.
However, if a player wants to minimize the number of playthroughs they need to do to obtain everything in MMBN4, they should make sure to pick up all BMD/PMD in the game before starting New Game +.
Mega Man Battle Network 5
Gold Cloud
English GBA version only.
Due to the removal of Gargoyle Comp 2 and Ship Comp 1, some chips can no longer be found in GMDs, making them one-time obtainable only during the clouds puzzle in Ch. 3.
| Chapter # | Missable item | Location | Alternative ways to get |
|---|---|---|---|
| Ch. 3 | (GBA-EN) (TP) ElcReel1 Z | Gold Cloud | (TC) ElecOgre (LV5~7), (TC) EleOgrEX (LV5~7) |
| Ch.3 | (GBA-EN) Thunder L | Gold Cloud | Chip Trader; can obtain Thunder * from Bargain Bin (1000z), SciLab Area 2 GMD (L1), End Area 1 GMD (L3) |
VacuProg Key Item
Japanese GBA version and Legacy Collection only.
If MegaMan interacts with the Boktai Trader in Oran Area 2 and declines to use Crossover Points before obtaining the VacuProg Key Item in the story, it can become permanently missable. When this happens, the story will proceed as if MegaMan already has the VacuProg as soon as he enters Oran Area 1 during Ch. 3, and you can get rid of the cyberclouds as normal, but the VacuProg item won't be in your Key Items.
Once the game is in this state, it is possible to get the VacuProg after all by obtaining a chip from the Boktai Trader, which will remove the VacuProg ability; then, without interacting with the Boktai Trader again, backtrack to Oran Area 1 and talk to Mr. Prog to obtain the VacuProg properly. However, this is no longer possible once the player defeats GyroMan (TP) / ShadowMan (TC).
This item is more easily missed in the Legacy Collection, since the Boktai Trader always appears on the Net, whereas in the GBA version, it only appears once the player has made a profile in the Crossover Battle mode.
Dark Chip NPCs
There are 2 certain NPCs that sell Dark Chips on the Net. If those chips are bought during Ch. 4 when the Leader Navi (ProtoMan/Colonel) is Lan's Navi, later going back to that NPC as MegaMan will give different dialogue than if MegaMan bought it.
| Location | If MegaMan bought it | If Leader Navi bought it |
|---|---|---|
| SciLab Area 4 (DarkWide) |
"Thanks for helping me out like that." "Don't try to give it back,either!" |
"This Navi helped me out by buying my" "weird-colored Wide- Sht I didn't like for 1000 Zennys." |
| End Area 1 (DarkDril - invisible path) |
"No refunds if that's what you want!" |
"Get outta my face. I ain't got time for the likes of you!" |
Mega Man Battle Network 5DS
In the BN5DS version of the game, some features will be skipped due to features using the W Slot function.
| Chapter # | Missable Item | Location | Alternative ways to get |
|---|---|---|---|
| Ch. 2 | BnusFldr (ExtraFolder) | When you receive the NaviCust E-Mail and already have BN5Fldr from the W Slot. | Available from a Navi in Kitchen Comp accessed via ACDC Area 2. |
Mega Man Battle Network 6
Legacy Collection
Exclusive to the Legacy Collection version. (These changes have been fixed in the July 2023 update)
There is an oversight which can cause the Virus Battler to use the wrong set of rewards. When playing on English language, the rewards given are the same as the GBA English version. However, the Legacy Collection version is based on the GBA Japanese version, which has a different set of rewards and various chips are obtained from different locations. As a result, playing on the English language can cause the player to miss certain rewards which are only obtainable from the Virus Battler.
Of particular note is the Django3 D chip, which is required for Mega Chip and Program Advance Library completion and which can otherwise only be obtained through multiplayer.

Rockman EXE 4.5: Real Operation
WindMan HP Memories
Due to a glitch, it is possible to permanently miss out on HP Memories for WindMan when the player is using multiple Navis and starts the day by using a different Navi, other than WindMan, which has progressed further in the story. If this is done too often, WindMan will be permanently unable to reach his maximum HP.

V2 boss ghosts
After defeating the V1 of a boss, its V2 ghost will appear invisibly in a set location. These ghosts can only be fought up until their V2 is fought as part of the boss rematches during the story. After that, the ghosts will despawn.
While this does not lead to missable content, as the V1 and V2 boss cards can also be obtained from their V3 random encounter, this is an easier way to collect those cards, as the V2 ghosts yield a reward screen after battle, unlike the story rematches.
