Metroid Zero Mission Randomizer (MZMR+) is a program initially created by biospark that allows you to randomize various aspects of Metroid Zero Mission, primarily item locations.
It has been expanded by Caption Glitch to include some additional options. It can randomize palettes, enemies, enemy stats, text, and music. It is only compatible with the North American (U) version of the game.
The program can also randomize certain ROM hacks. As of right now, the supported hacks include: Deep Freeze (logic by Captain Glitch) and Spooky Mission (logic by Captain Glitch and Conner). Certain options are disabled when randomizing hacks.
Features
- Item randomizer.
- Enabling custom music (Credit to JRP and Xl for the tracks).
- Randomizing enemy drops.
- Randomizing enemy weaknesses.
- Randomizing enemy damage.
- Randomizing enemy health.
- Specific options for Text Randomization.
User guide
Open an unmodified ROM of Metroid Zero Mission. ROMs that have been previously randomized are not usable.
Once the ROM is open, choose from various randomization settings. Each setting comes with tooltips explaining their functions.
Settings can be reused by saving them to a file, or you can load them from a string (found post-randomization or in a log file).
You can specify a seed for randomization (a number between 0 and 2147483647) or leave it blank for a random seed.
Click the gear icon for application settings, enabling time-saving options. Options include loading the previous ROM, saving log files, and map images.
Items
Randomize abilities, tanks, or both, including the removal of up to 90 items (those are marked as collected on the minimap).
"Game Completion" setting imposes location restrictions:
- If "No logic" is selected, there are no restrictions. However, you will immediately get stuck if Morph Ball is not the first item.
- "Beatable" means enough items can be obtained to beat the game.
- "100%" means that all items can be obtained.
There are two settings that remove item requirements, since they may be located somewhere inaccessible. One makes Metroids vulnerable to missiles when not frozen; the other makes black space pirates vulnerable to beams other than Plasma. Neither of these items is required elsewhere.
"No PBs before Chozodia" restricts Power Bomb locations, preventing early access and necessitating the Mother Brain fight.
"Chozo statue hints" make Chozo statues reveal item locations. Leave unselected for no hints.
Locations
You can specify actions for items at each location. Default includes every item in the randomization pool.
Choose to leave it random, remove the item, or set it to a specific one.
Detailed list of locations and their original items is provided in the readme.
Palettes
Randomize tilesets, enemies, Samus, and beams' colors by changing the hue.
You can specify a hue rotation range between 0-180 degrees.
For each palette, the hue is randomly rotated clockwise or counter-clockwise by a random amount within the range.
Text
You can randomize various in-game text from files in the Text folder.
To create custom strings, simply edit one of the files. Refer to the readme for formatting.
Music
Randomize room and boss music; enable custom music (Credit: JRP and Xl).
"No Logic" assigns any valid track randomly; "With own pool" ensures that each song is replaced with only one other song.
Stats
Randomize enemy stats (health, damage, drop stats) based on defined percentage ranges.
Drop stats are randomized for enemies to give them different drop values than they normally would.
Certain enemies are excluded from specific stat changes to prevent softlocks.
Misc
There are varies options that affect gameplay. The "Obtain unknown items" is taken into account by the "Game Completion" setting.
There's an option to randomize enemies, but it's somewhat limited for now.
There is an option to randomize bosses from a pool. Those bosses are affected by stat and palette randomization.
Boss health is scaled based on which location the boss is chosen to reside in.

Known issues
(v1.2) There are still issues with the .exe being flagged as malware.

- Modified text rando code to auto format strings based on bracketed expressions and length.
- Added Mega Core X to boss rando.
