A randomizer for Metroid Zero Mission, created by biospark with item placement logic by Dragonfangs, allows randomization of various elements in Metroid Zero Mission, primarily focusing on item locations. It's compatible only with the North American (U) version of the game.

Features

• Randomize item locations.
• Randomize palettes.
• Randomize enemies (somethat limited).

User guide

To start, open an unmodified Metroid Zero Mission ROM. ROMs that have been previously randomized cannot be used.

Select randomization settings from a variety of options. Tooltips are available for each setting, explaining their functions.

You can reuse settings by saving them to a file and loading them later. Seed for randomization is optional.

Items

Randomize the location of abilities (e.g., Wave Beam, Hi-Jump), tanks (Energy, Missile, Super Missile, Power Bomb), or both. You can also remove up to 90 items, those are marked as collected on the minimap.

The "Game Completion" setting imposes item location restrictions:

• "No logic" has no restrictions, but getting Morph Ball first is vital.
• "Beatable" ensures enough items to finish the game.
• "100%" guarantees obtaining all items.

There are two settings that remove inaccessible item requirements. One makes Metroids vulnerable to unfrozen missiles, and the other makes black space pirates susceptible to non-Plasma beams, with no requirements elsewhere.

"No PBs before Chozodia" option restricts Power Bomb locations, preventing early Chozodia entry. Softlock prevention is applied if Power Bombs are obtained before Bombs.

"Chozo statue hints" shows item locations on Chozo statues. If unselected, Chozo statues provide no hints.

Unskilled at bomb jumping or wall jumping? Leave these options unselected. It ensures these tricks aren't required for beating the game ("Beatable") or collecting all items ("100%").

Locations

Specify actions for each item location: random, remove, or set to a specific item.

Refer to the readme for the list of original items and their locations.

Logic

Choose default logic or your custom logic by selecting a file. You can also specify tricks for the logic to consider.

If you are not skilled at bomb jumping or wall jumping, leave these options unselected. This ensures these tricks aren't mandatory for beating the game ("Beatable") or collecting all items ("100%").

Rules

Specify rules to modify item placement, allowing inclusion or exclusion in certain locations or areas.

Adjust the placement timing during randomization.

Palettes

Randomize tileset, enemy, Samus, and beam colors by rotating the hue within a specified range (0-180 degrees).

Misc

Various gameplay-affecting options are available, such as enhancing unknown item acquisition.

Limited enemy randomization features are present.
