Change Log

  • 2023/07/17

    Here is a mini-release with several bugfixes from the recent one, and a graphical change based on user feedback.

    The most visible change is a font adjustment. Vanilla font has been brought back for item collection message boxes. The custom font, used for HUD and pause menu, has been replaced with another that is closer to vanilla in style, and we added lowercase letters.


    • fixed credits regression on race seeds
    • fixed issue with objectives reading in auto-tracker
    • fixed customizer compatbility issue with older seeds
    • use default value for missing parameters when calling randomizer from web service
    • added missing Maridia objective in objectives_hard_water preset
    • added missing parameters in usage statistics page

    Hello @randomizer,

    We've released a new version of the VARIA Randomizer, Solver, Tracker, Plandomizer and Customizer (

    🪞 You can now play the game horizontally mirrored! This has been made possible by integrating the Super Mirrortroid hack by @BuggMann ( In mirror flavor all rooms, including bosses/mini-bosses are mirrored. All VARIA features are available in both vanilla and mirror flavors.

    🗒️ The recently introduced objective system has been extended. There is now a distinction between "possible objectives" (the objective list in the seed) and "required objectives" (the actual number of objectives to complete from this list). This allows for more strategic play, by completing objectives that work well together. For this to be interesting, we had to expand the maximum number of objectives (9 max required, 18 max possible). Try it out with the "objectives_bingo" settings preset!

    🗺️ The in game map has been enhanced as well, using the awesome Map Overhaul patch by @MFreak as a base. The room connections are visible, as well as major/minor item locations adapted to the seed's item split. Each VARIA area has its own color, consistent across the vanilla area maps. The door colors and area/boss portals are dynamically tracked and shown as map icons. When applicable, objectives are visible on the map.

    ▶️ Speaking of map, the tracker/plandomizer user interface has been remade by @chrisc! On top of mirror support it features seamless change of map style, smooth resizing, different item trackers, an improved seedless mode etc.

    Other new stuff:


    • objectives: new map completion based objectives
    • objectives: new "Hidden objectives" option for random objectives: the objective list is hidden until you reach G4 (or equivalent)
    • rom: improved objective screen with detailed progress display
    • rom: new ending screen showing RTA time, item%, and item collection details
    • rom: show RTA timer in the pause menu
    • rom: new HUD/message boxes/pause screen font
    • rom: restored vanilla Mother Brain cutscenes
    • doors: no plasma doors when super fun combat is on
    • presets: save/load rando presets to/from disk
    • layout: in area rando, removed the platform in green hill zone (reduced the above overhang instead)


    • hellruns: only account for a maximum of (number of ETanks+1) Reserve tanks
    • New techniques :
      • Spore Spawn backdoor (enabled by default in existing presets, disabled in newbie)
      • Mirrored Wave Gate Glitch: GGG from a wall jump at Wave Gate in Mirrortroid (veteran+)
      • Mama Turtle wall jump bomb boost (expert+)
      • East Sand Hall Spring Ball Jump (master)
      • West Sand Hall Insane Bomb Jump (master)
      • Cacatac Alley Underwater Wall Jump (master)


    • escape path is shown in solver spoiler log
    • auto-tracker support for multiworld seeds (thanks @Dorkmaster Flek for the PR)


    • added a LOT of new sprites and ships
    • improved palette randomization of levels, by adapting to human perceived luminance
    • option for Hard Mode by @Sirkura, @Devaliah, @Quote and @Phosphodile
    • option to add VARIA RTA timer/stats/credits to a vanilla ROM


    • rando: prevented speedrun progression speed from generating seeds above max required difficulty when it was not necessary
    • patches: don’t open Ridley door when he’s dead when HUD is on in non-Scavenger seeds
    • logic: added missing access to Mickey Mouse missiles from Firefleas (was previously only in logic from LN entrance)
    • and more...

    Hello @randomizer,

    We've (finally!) released a new version of the VARIA Randomizer, Solver, Tracker, Plandomizer and Customizer ( This is a pretty humongous one.

    You can now choose the objectives required to trigger the endgame. The endgame itself can be Vanilla Tourian, Fast Tourian, or just trigger the escape sequence. It is of course possible to randomize these settings, and they are fully supported in the Solver/Tracker/Plandomizer as well.

    Objective settings are in the Medium or Advanced tab of the Randomizer page. Choose or randomize from 0 to 5 objectives, from a pool of 37 possible goals about bosses, mini-bosses, area/item completion, or memes! Be sure to use the help (?) button of the setting for details.

    At any point, objectives status can be checked in the pause screen, along with an item% indicator (useful for item% related objectives). When objectives are not vanilla, the G4 statue sound effect is played when an objective is completed, and a notification is displayed if VARIA HUD is enabled. Objectives and Tourian status are also recalled before starting the game when they are not vanilla.

    Special thanks @chrisc for your contributions to the web front-end!

  • 2021/08/02

    Hello @randomizer,

    We've released a new version of the VARIA Randomizer, Solver, Tracker, Plandomizer and Customizer ( featuring a new HUD and an auto tracker!

    The HUD is used in two brand new majors split :

    • Full Countdown: Randomize like Full and display in the HUD the number of remaining unique upgrades (everything but energy and ammo) in the current area.
    • Scavenger (thanks to @Slappy for the idea!): you must visit a given number of locations in a mandatory order in a scavenger hunt, and collect items there. The scavenger locations are the 16 locations where a unique upgrade is in the vanilla game. The HUD shows the next location in the hunt (whole route available in the pause menu). You can choose how many locations will be in the hunt (between 4-16, defaut is 10), whether the items in the hunt locations will be vanilla (default), or whether the escape is immediately triggered when the hunt is over (by default, you still have to beat G4 and go through Tourian after the hunt is over). The remaining unique upgrades will be randomized between the remaining scavenger locations.

    The HUD also enables the usage of Major/Chozo split with random start location (some locations are changed, so the HUD is used to know how many Major/Chozo items are left in the current area). It can also be used as a standalone comfort patch. The area names in the HUD are the ones used by the area randomizer, so mind that Crocomire and Kraid’s Lair are their own areas for example. You can play around with the options and/or try out the new settings presets starting with ‘hud_’ or ‘scavenger_’ to enjoy the new modes!

    Also featuring the VARIA Auto-Tracker to automatically track Area/Boss transitions, collected Items and Door colors as you play the seed, as long as you play on a platform compatible with QUsb2Snes.

    Other new stuff:

    • tracker: highlight accessible rooms on the map
    • tracker: reset door colors when clicking on items bin
    • solver: removed minimal pickup strategy, only any% and 100% now
    • rando: slight credits rework
    • rando: new ‘nothing’ item PLM to avoid having an extra missile pack in some cases
    • rando: detect headered ROM and automatically remove the header
    • rando: always load ‘default’ setting preset before loading a settings preset
    • rando: tips are now always displayed on top of the page
    • customizer: new sprites: Enby Samus by @Glove, Shaktool Jr by @Pneumatic
    • customizer: more custom items names for sprites by @Avatar: Sprite Can, Link, Megaman, Win95, Mario/Luigi
    • customizer: new custom sprites/ships will now be added independently from main releases
    • customizer: option to restore vanilla music

    Hello @randomizer,

    We've released a new version of the VARIA Randomizer, Solver, Tracker, Plandomizer and Customizer (

    Now you can start your seeds from somewhere else than Landing Site (or Ceres). Choose a start location, or randomize it! Click on the attached screenshot to check out the start locations list (note: Red Brinstar Elevator and Golden Four are only available in Area rando).

    Thanks to folks in the VARIA Randomizer discord ( and #data-dev channel in SMZ3 discord for some of the starting locations ideas!

    Important notes:

    In area rando, the Key Hunter Room bottom door (vanilla door to Red Brinstar Elevator) and the vanilla door to G4 are now blue, since Crateria is no longer necessarily the start area.

    Early morph setting had to be modified to accomodate this new feature, and this has some significant consequences on standard start seeds with Early morph (like all tournament presets, so read carefully):

    • Speed or Screw attack can now be in Blue Brinstar even with Early Morph enabled

    Hello @randomizer,

    We've released a new version of the VARIA Randomizer, Solver, Tracker, Plandomizer and Customizer (, dubbed "MegaSamus X"!

    You can now change Samus sprites in the customizer. All the sprite sheets created so far with SpriteSomething ( have been integrated, for instance Megaman X!

    Another cool new feature is the ability to use the Randomizer to complete your plando. This allows for fun stuff like creating your own custom map (you don't like Wrecked Ship? don't include it) for your seeds, or generate a seed after placing Varia at Ridley for example.

    Note: to remove the bloat of the randomizer page, color randomization is now only available on the customizer page, don't worry it has not gone away!

  • 2018/05/01

    Hello @randomizer,
    We've released a new version of the VARIA Randomizer dubbed "Randomize the Randomizer":

    • New options to randomize the parameters used by the Randomizer
    • The parameters used are now displayed in the credits
    • As we had for Bosses and Hellruns, we now have difficulties for hard rooms: X-Ray and Gauntlet, so we've removed a few techniques for these rooms
    • Now there's techniques for better settings of Gravity-less movement underwater
    • New Randomizer's parameter to influence choice of the next location based on its difficulty
    As a result don't forget to update your presets before using the Randomizer.

  • 2018/04/21

    Hi @randomizer!
    We updated the VARIA ( to fix two issues:

    • 1) The "too much spospo" bug. Now, the probability you would have to fight it is ~30% in slowest/slow, ~5% in medium, and ~0% in fast/fastest. All in all if you choose a random speed, there is a 1/7 chance to have to do the fight.
    • 2) When "start at Ceres" was selected instead of "start at landing site", the stats counters in the credits were wrong and glitched out. It is now fixed, thanks @andrew (original credits/stats patch author), Smiley and PJBoy from metconst for their help, this was a tricky one to fix.

  • 2018/04/14

    We've made a new release for the VARIA Randomizer (

    • the layout patches are now optional (for EasyDanger)
    • the save the animals suprise patches are now available (for andrew)
    • there's now a tutorial and contextual help to explain the parameters of the Randomizer and Solver in greater details
    • the randomized ROMs are now generated a lot faster (between x2 and x3 gain)

  • 2018/04/09

    Hi @randomizer !
    We made an update to the VARIA randomizer and solver ( ). Not much in terms of new features, but lots of work behind the scenes:

    • stabilized and improved randomizer algorithm: now it can be trolly with minor items as well (especially in slow/slowest speeds), be sure to try it! ;)
    • fixed logic bugs affecting both rando and solver
    • fixed Normal/Hard Total ROM patch set mapping for solver
    This is an intermediate release, there's more in the works, namely: drastic performance improvements, a tutorial for the website explaining the plethora of settings and other surprises!

  • 2018/03/16

    Hello @randomizer !
    We updated the VARIA ( Among the obligatory bugfixes, the following new features are available:

    • Skip intro/start at Ceres option, as suggested by @Di10 and @BlackEliteJohn
    • Added optional patch to speed up doors and elevators transitions

    • Ability to have a random progression speed instead of choosing one

  • 2018/03/13

    @randomizer Hello,
    Using the presets (for each technique you can say if you know it and your perceived difficulty for it) from the solver we've made a new randomizer: the VARIA randomizer (Very Adaptive Randomizer of Items for Anyone)
    It can be found here:
    Its features:

    • generate a randomized ROM which can be finished using the techniques of the given preset
    • can limit the max difficulty for reaching a location
    • can choose the probability of each minors and the percentage of minors available
    • can choose the quantity of Energy/Reserve Tanks
    • can do a full randomization of the majors
    • can influence how fast the randomizer places the progression items
    • can spread the progression items in all areas with maximum distance between them
    • several optional patches are available:
      • allow the aim buttons to be assign to any button
      • remove fanfare when picking up an item
      • allow Samus to start spinning in mid air after jumping or falling
      • play the music with MSU1 chip on SD2SNES

  • 2018/01/30

    We've added a few things to the randomized roms solver (

    • display the number of techniques used to solve the rom
    • in the spoiler display the techniques used for each location
    • for each techniques display the rooms where it's used with links to the wiki
    • update the CSS of the website

  • 2018/01/22

    With a friend we've developed a solver for the randomized Super Metroid roms:
    Tell it what you know (and how hard you find particular tricks), and it'll tell you if you can finish your seed, and how hard it will be, without spoiling the seed.
    It's useful for people who hasn't yet mastered all the Super Metroid tricks required by the randomizers.

    • works with randomized roms from Dessyreqt randomizer and (Total, Foosda, Leodox) randomizer
    • somewhat realistic navigation algorithm
    • pretty much all tricks and difficult rooms/areas have their setting, with video explanation when we found one, so you can actually learn the tricks if you want
    • website front end
    • save/load your presets on the website without having to create an account
    • boss difficulty is estimated as well
    • hell runs are taken into account in navigation
