Version History ----------- 1. Overview ----------- Metroid Zero Mission Randomizer is a program created by biospark (with item placement logic by Dragonfangs) that lets you randomize various aspects of Metroid Zero Mission, primarily item locations. It can also randomize palettes, enemies, and other types of randomization are planned for the future. It is only compatible with the North American (U) version of the game. Bug reports and questions should be directed to the MZMR thread on the Metroid Construction forums: http://forum.metroidconstruction.com/index.php/topic,4559.0.html You can also find the latest updates and releases there. -------- 2. Usage -------- To start, open an unmodified ROM of Metroid Zero Mission. ROMs that have been previously randomized cannot be used. Once the ROM is open, you can select a variety of randomization settings. All of the settings have tooltips if you hover over them, which explain their functions. You can reuse settings by saving them to a file and loading them later. You can also load settings from a string, which can be found after randomization or in a log file. You can specify the seed to use for randomization, which must be a number between 0 and 2147483647. If left blank, a random seed will be chosen. Unless you're using the same seed and settings as someone else, there's no reason to provide a seed. -------- 3. Items -------- You can randomize the location of abilities (such as Wave Beam, Hi-Jump, etc.), tanks (Energy, Missile, Super Missile, Power Bomb), or both. You can also remove up to 90 items. Removed items are marked as collected on the minimap. The "Game Completion" setting places restrictions on where items are located. 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, and the other makes black space pirates vulnerable to beams other than Plasma. Neither of these items is required elsewhere. The "No PBs before Chozodia" setting places restrictions on where Power Bombs are located. No Power Bombs can be obtained to enter Chozodia early, forcing you to fight Mother Brain and do the suitless sequence. Normally the game will softlock if you obtain Power Bombs before Bombs, but the game has been modified to prevent this. The "Chozo statue hints" setting makes Chozo statues show the new location of each item. For example, the very first Chozo statue in the game will show where Long Beam is. If left unselected, Chozo statues won't show any hints. ------------ 4. Locations ------------ You can specify what to do with the item at each location. By default, every item is included in the pool for randomization. For each location, you can leave it as random, remove the item, or set it to a specific item. Below are all the locations and their original items. You can also find the item numbers on the included map images. 0 Brinstar (0, 15) Morph Ball 1 Brinstar (5, 14) Missile Tank 2 Brinstar (6, 6) Long Beam 3 Brinstar (7, 15) Energy Tank 4 Brinstar (9, 11) Missile Tank 5 Brinstar (9, 12) Super Missile Tank 6 Brinstar (11, 3) Missile Tank 7 Brinstar (11, 12) Missile Tank 8 Brinstar (14, 2) Varia Suit 9 Brinstar (14, 12) Charge Beam 10 Brinstar (16, 3) Energy Tank 11 Brinstar (16, 12) Missile Tank 12 Brinstar (17, 7) Missile Tank 13 Brinstar (17, 10) Missile Tank 14 Brinstar (22, 8) Missile Tank 15 Brinstar (23, 4) Missile Tank 16 Brinstar (23, 6) Missile Tank 17 Brinstar (24, 6) Bomb 18 Brinstar (24, 8) Energy Tank 19 Kraid (3, 5) Missile Tank 20 Kraid (6, 6) Missile Tank 21 Kraid (7, 9) Missile Tank 22 Kraid (7, 12) Missile Tank 23 Kraid (7, 14) Space Jump 24 Kraid (8, 8) Missile Tank 25 Kraid (8, 15) Speed Booster 26 Kraid (11, 4) Missile Tank 27 Kraid (11, 6) Missile Tank 28 Kraid (12, 10) Missile Tank 29 Kraid (13, 2) Energy Tank 30 Kraid (13, 7) Energy Tank 31 Kraid (15, 4) Missile Tank 32 Norfair (3, 11) Power Bomb Tank 33 Norfair (4, 12) Missile Tank 34 Norfair (6, 7) Screw Attack 35 Norfair (8, 7) Missile Tank 36 Norfair (10, 5) Missile Tank 37 Norfair (10, 6) Missile Tank 38 Norfair (10, 12) Wave Beam 39 Norfair (11, 6) Super Missile Tank 40 Norfair (11, 13) Missile Tank 41 Norfair (13, 13) Missile Tank 42 Norfair (14, 6) Missile Tank 43 Norfair (15, 10) Missile Tank 44 Norfair (17, 10) Super Missile Tank 45 Norfair (18, 3) Ice Beam 46 Norfair (19, 2) Missile Tank 47 Norfair (19, 8) Hi-Jump 48 Norfair (20, 4) Missile Tank 49 Norfair (21, 1) Missile Tank 50 Norfair (21, 11) Energy Tank 51 Norfair (22, 8) Missile Tank 52 Norfair (22, 11) Missile Tank 53 Ridley (3, 8) Missile Tank 54 Ridley (3, 9) Missile Tank 55 Ridley (4, 6) Missile Tank 56 Ridley (5, 7) Energy Tank 57 Ridley (6, 7) Gravity Suit 58 Ridley (7, 3) Energy Tank 59 Ridley (8, 4) Missile Tank 60 Ridley (8, 5) Missile Tank 61 Ridley (9, 1) Super Missile Tank 62 Ridley (9, 4) Missile Tank 63 Ridley (9, 5) Super Missile Tank 64 Ridley (10, 8) Missile Tank 65 Ridley (12, 5) Missile Tank 66 Ridley (13, 5) Missile Tank 67 Ridley (14, 4) Super Missile Tank 68 Ridley (16, 6) Missile Tank 69 Ridley (17, 7) Energy Tank 70 Ridley (19, 2) Missile Tank 71 Ridley (22, 7) Missile Tank 72 Ridley (24, 5) Missile Tank 73 Tourian (17, 11) Missile Tank 74 Tourian (19, 12) Power Bomb Tank 75 Crateria (9, 4) Power Bomb Tank 76 Crateria (14, 6) Power Grip 77 Crateria (17, 8) Missile Tank 78 Crateria (19, 5) Missile Tank 79 Crateria (20, 5) Plasma Beam 80 Crateria (21, 5) Missile Tank 81 Crateria (22, 2) Super Missile Tank 82 Chozodia (4, 18) Power Bomb Tank 83 Chozodia (4, 21) Super Missile Tank 84 Chozodia (6, 21) Super Missile Tank 85 Chozodia (7, 19) Super Missile Tank 86 Chozodia (10, 7) Missile Tank 87 Chozodia (10, 8) Super Missile Tank 88 Chozodia (10, 9) Power Bomb Tank 89 Chozodia (10, 18) Energy Tank 90 Chozodia (11, 13) Super Missile Tank 91 Chozodia (14, 5) Power Bomb Tank 92 Chozodia (15, 4) Power Bomb Tank 93 Chozodia (15, 13) Power Bomb Tank 94 Chozodia (17, 8) Energy Tank 95 Chozodia (18, 7) Super Missile Tank 96 Chozodia (20, 7) Super Missile Tank 97 Chozodia (21, 15) Super Missile Tank 98 Chozodia (22, 2) Energy Tank 99 Chozodia (26, 14) Power Bomb Tank -------- 5. Logic -------- You can choose whether to use default logic for item placement, or use your own custom logic by selecting a file. You can also specify which tricks you want the logic to account for. For example, if you aren't skilled at bomb jumping or wall jumping, you can leave these options unselected. This will ensure that these tricks are never required to beat the game (if you selected "Beatable") or collect all the items (if you selected "100%"). -------- 6. Rules -------- You can specify rules that modify item placement. This allows you to place or exclude items in certain locations or areas. There are also options to change how early or late an item is placed during the randomization process. ----------- 7. Palettes ----------- You can randomize the colors of tilesets, enemies, Samus, and beams. This works by changing the hue of each palette (much like rotating a color wheel). You can specify the 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. ------- 8. Misc ------- There are a variety of options you can select that affect gameplay, most of which are enhancements. The option "Obtain unknown items" is taken into account by the "Game Completion" setting. There's also an option to randomize enemies, but it's somewhat limited for now. More enemy randomization features may be added in future updates. -------- 9.
