About This File

This is a Python 2 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 can be found in the included NOTES.txt.

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. Make sure you read the NOTES.txt!

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.
  • 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 3.9.4   See changelog

Released

  • Updated the list of randomizable Virus Names with over 600 new names!
  • Updated the list of randomizable Chip Names with almost 50 new names. More to come eventually, I'm sure.
  • Updated the list of randomizable Stages to further attempt to stop players from spawning on Lava Panels. Any stage with a Lava Panel in the center back or center middle panel has been completely removed for now. I'll add more stages later.
  • Fixed some bugs with the Folder Lock Mode again. It should work properly now, finally.

Known Issues:

  • Unsurprisingly, as it turns out, changing the Battle Chip codes breaks Program Advances, and I have no idea how to fix that as the PA data isn't as easily available to find as the chip data is. Consider this a head's up for those wanting to play around with Simplified or Chaos Chip Code Roulette Modes.
  • Some BBS Jobs may be incompleteable if you shuffle around Trade Requirements. This is a bug, but it's not an easy one to fix on my end, due to how I'm handling both Trades and BMDs.
