MMBN Randomizer

MMBN Randomizer is a Java utility that “randomizes” a Mega Man Battle Network ROM. Things being randomized include chip codes, chip drops and enemies in random encounters.

To run this program, Java 8 must be installed on your computer.

Usage

Run the MMBN Randomizer like any other JAR file. If no command line arguments are provided, a GUI will be displayed.

java -jar MMBNRandomizer.jar inputrom [outputrom [seed]]

To use the MMBN Randomizer from the command line, pass it the file path of the input ROM. You can also pass it the path of the output ROM and, if you do that, the seed to use for randomizing the ROM (as a decimal 32-bit signed number).

Compatibility

Currently MMBN Randomizer works for the following games:

• Mega Man Battle Network 6: All versions.
• Mega Man Battle Network 5: All versions.

Since all chip codes are randomized, save files are locked to the seed that was used. If you use a save file from the clean ROM or a randomized ROM with a different seed, the game will softlock when you enter folder edit and you can’t use any of your chips in battle.

Notes

• This is still very much a work-in-progress, so many parts have not yet been polished.
