About This File
This is a Python 3 script with a bunch of text files used for randomizing Mega Man Battle Network 3. I've taken some liberties to make it more interesting to use. Credit goes to Mountebank/Samfin, Dabomstew, Prof.9, Rockman.EXE, and potentially other people I don't know about/forgot for the original MMBN3 Randomizer I found on Github.
Features
- Supports both Version White and Version Blue! Thanks, Hart-Hunt!
- The original randomizer featured randomizing of Numberman Code Prizes that give Battle Chips, Battle Chip Folders, Green Mystery Data, and Virus Formations. Those are still here!
- Lots of text files. They hold a bunch of data that you can mess around with to some extent. Just be sure to back things up in case something goes wrong.
- Various modifiers are asked of you right off the bat when opening the script. These include Battle Chip Damage and Enemy HP Multipliers and Variance Values, as well as a Custom Run seed and a "Chip Code Roulette" Mode!
- If a Run Seed is not supplied, it will generate one based on the current time.
- More details, including sourcecode, potentially newer builds, and other resources can be found at the program's Github page, located here.
Known Issues/Caveats
- The rom must be a clean US copy of Mega Man Battle Network 3.
- Messing with the text files in ways you probably shouldn't mess with can lead to errors, crashing, corrupt ROMs, etc. I take no responsibility for any of this.
ROM Checksums
These checksums are from a clean, self-dumped MMBN3 White rom. If you're going to use this randomizer, you'll need a rom that has these checksums.
- CRC32: 0BE4410A
- MD5: 68817204A691449E655CBA739DBB0165
These checksums are from a clean MMBN3 Blue rom. If you're going to the use this randomizer, you'll need a rom that has these checksums.
- CRC32: C0C780F9
- MD5: 6FE31DF0144759B34AD666BADAACC442
Open Mode Patches
These patches can be used if you want to experience the game in a different way. Make sure to patch the rom with the correct patch BEFORE randomizing it! The features of these patches are listed below.
-
A built-in Full Library code! This took a while to figure out.(This has been recently disabled.) - Every area of the game should be open to the player right off the bat.
- You start the game with every email, access to the NaviCust and StyleChange menus, as well as some NCP programs and Key Items for access to various areas.
- Style Changes happen more frequently.
- You have 4 out of the 7 Savefile Stars unlocked right off the bat! No need to fight Serenade, the Omega Navis, or do the Time Trials unless you want to.
- Code for most of this new version of the Open Mode patch provided by NMarkro, a member of TeamBN. Thanks again!
The Open Mode patches, either in combination with the Randomizer or not, can be used for various types of play. Here are a few ideas:
- Bingo Races
- Alpha or Serenade Races
- Time Trial Races or Practice
What's New in Version 5.3 Hotfix See changelog
Released
Lots of changes since I've posted a release here!
-
Version 5.2.0.1
- Cleaned up how chips are shuffled. They are now PROPERLY SHUFFLED instead of generating multiple permutations.
- Fixed an accidental "not" case with Unlocked Unlimited, preventing it from uncapping Gigas and Megas.
- Rebalanced Daily Seeds to be more interesting.
- Properly implemented the Omega Navi toggle, albeit somewhere else in the game. It's now toggled at the Undernet Server, where you jack into the Secret Area.
- Removed the "Unlocked Unlimited" Folder Lock Mode since it never functioned correctly (Whoops). It's also more than likely a bad idea anyway.
-
Version 5.2.1
- Fixed the "Enable Omega Navis" toggle both not working as intended and unintentionally crashing the game due to being assigned the incorrect location to read from in ROM. Don't delete or move the external "enableomega.bin" file, as it's required.
- Fixed the Command Line program still referencing the "Unlocked Unlimited" Folder Lock mode even though it no longer exists.
- The Randomizer now assigns a clean copy of the Seed before doing each task. This should allow for more consistent randomization between the two versions as long as they have the same settings, though I can't vouch for it too well.
- Included Punk in Navi randomization, moved BowlMan and MistMan to "Strong Navis", and moved PlantMan and DesertMan to "Medium Navis".
- The Output log filename is a bit shorter now while still listing the version and hash.
- Made sure MistMan and BowlMan could actually be shuffled out instead of just being able to be shuffled in, thus preventing duplicate encounters.
- Made sure the Navi shuffling took into account the new list numbers.
-
Version 5.3
- Forced the Standard Library, Mega Library, and PA Library Stars on the Title Screen to always be active. I did this by making their requirements 0.
- Fixed the Secret Area Doors code from being inserted into the wrong list. This also allows the above change to work.
- The Zenny Multiplier can no longer ignore limits when used with the "Ignore Limiters" setting to prevent major Zenny drops from being multiplied too heavily.
- BMD/PMD Zenny text is no longer changed to both prevent issues with potentially changing the text boxes and so I can increase how much Zenny they give without needing to worry about the mismatched text. They are now properly multiplied instead of capped at certain digits like before.
- Fixed a bug where the Navi Randomization lists were the wrong size whenever it resets the lists in the main function, thus resulting in an error.
-
Version 5.3 Hotfix
- Accidentally wrote to the wrong Zenny value when randomizing BMD/PMD values, resulting in bugged textboxes in a lot of locations and potential softlocking. This has been addressed.
