Hello. Made an account to report a bug.
I randomized a few seeds, and randomizing enemies seems to be always-on, despite the checkboxes. After encountering this (first room Zoomers were Geemers), I generated a few test seeds. Resulted in never once having a proper Zoomer in the first two rooms.

I would provide images, but this is my first post on the forum, so I cannot.

As for settings, the following are True: Abilities; Tanks; Beatable completion; Ice beam not required; IBJ; Wall jumps; All Palettes; Item Toggle; HM available; Cutscenes off; Obtain Unknown Items; Skip suitless

The latest update really gave the MZM Randomizer new life. Really enjoyed it!

[shanely]

Experiencing a bug where Setting location 76 to its default item (power grip) yields the error "Randomization failed. Try changing your settings." Changing it back to random generates a ROM.

[Kauzmoedon]

This is due to how Location 76 is coded, because like most Crateria locations, it requires that Location 36 (the missile on the way to the Norfair/Crateria elevator) be reachable. If you have IBJs turned off for the logic, this makes it so Grip must be required for location 36, and since 76 is locked by 36, it fails the logic and fails to be randomized.

On another note, I'm having difficult understanding the coding behind Location 50 (Energy Tank behind Larva). This is what I'm seeing when I decompile:

Code Select Expand

        case 50:
          if (!this.NorHeatRun || !this.Speed || !this.CeilingTunnel_3_4)
            return false;
          return this.Bomb || this.PowerX(1) || this.ActivePlasma;

Nowhere in this is a requirement for Wave Beam, which can yield a scenario where Wave Beam is in Location 50. In doing research I was able to find a method of getting through the room prior to the larva without Wave Beam, but that method also required Long Beam, which is also not listed as a requirement. Am I missing a method to get through the heated room before the larva without Wave or Long? Is there some fancy Shinespark shenanigan I am missing?

For reference, here is the seed info where I encountered this:
Seed: 1342091802
Settings: 6pITLGO_A

pretty sure screw is optional, but it makes things easier.
there's also https://www.metroid2002.com/0/other_norfair_without_wave_beam.php

[Kauzmoedon]

That would be the method I was missing! Thank you :)

The second one you linked is the one I originally found, but doing that method with only 200 energy would be really rough.

[MetaEdge]

Found what I believe to be an unwinnable seed

Seed: 1197315954
Settings: NyITLYO_B

The issue is that hi-jump is locked by bombs in brinstar (shortcut room going from kraid to norfair), and bombs are locked by hi-jump in criteria (plasma room, the location near the door).

Seed: 1679648454
Settings: StITTcwX



Is Speed Booster really locked behind itself (and Gravity Suit) or is there some other way in there that a power bomb doesn't show? If not, is this seed still beatable?

[caauyjdp]

You've set randomizer to beatable, so yes, some things can become ungettable like this.
Speedbooster isn't required to beat the game tho, there's another way to lower norfair.

Well, I didn't know Speed Booster wasn't required. Thanks.

Wait, isn't Wave Beam also needed? Because Wave Beam is in the image here, where I need Speed Booster to get to it.

[shaktool7]

Are you aware of the shortcut which allows ridley first? IIRC, that should be it, by that, I mean the righter most green strip in norfair in this map

[Proxima Ace]

I was not. Either way, I've decided that I'm gonna do 100% instead of beatable from now on.

[Belmont]

Is it just for me or is the Download link not working anymore? I'm using google chrome

[LetsPlayNintendoITA]

tried it just now it works

[Belmont]

tried it now too on Microsoft Edge. Still won't let me download on Google Chrome. Maybe its a browser Problem. Thanks for replying :D

[Kewlan]

Many thanks for this. I've beaten lots of seeds and it's fantastic!

One request I have is to make the gravity suit, when it's without the varia suit, to:
- Be blue re-color of the varia suit
- Not prevent lava damage
- Only halve damage

Another request is to have the map stations gray-reveal every map tile, just so people like me who forget some hidden locations don't have to put away the game to look it up.

[Zeke]

Is it possible to escape the Chozo Test area without gravity? I can make it out of the water, but the lava seems to be inescapable.

(Btw, awesome rando, biospark. I should've tried it long ago.)

[RT-55J]

IIRC I saw a speedrunner fella make that lava dive in a plando seed the other day. The requirement is a few tanks worth of energy (like at least 3 I think) and maybe varia (idk). Not sure if space jump would make things better or worse there.

Anyhow, as for the randomizer itself, I would like to request the option of shuffling the abilities and energy tanks in the same pool, like how the major/minor split works in other Metroid randomizers.

Also, I played two seeds this week where I beat Mother Brain, and both of them had me start at the beginning of the suitless sequence (rather than next to Charlie) despite having the "Skip Suitless Sequence" box checked. I'm assuming this is unintended, or that I'm just being a dummy. (One such seed was Seed: 1830480900, Settings: 33oAmc5Thf)

Also hi Zeke how's it going?

[Zeke]

Not bad, yourself? Nice to see a fellow m2k2er. It's ironic that the board was archived just in time for Prime rando to breathe new life into the game that started it all -- all the old tricks are relevant again.
