Hyper Metroid Item Randomizer

Command Line Interface (CLI) edition fork by strotlog

Works on various platforms including Linux and macOS!

How to use CLI

Prerequisite 1: Install the .NET 6 SDK Get from dot.net/download and install

Prerequisite 2: Generate the base rando ROM:

git clone https://github.com/strotlog/HyperMetroidRandomizerCLI
Copy your unheadered, legal backup of Super Metroid to 'HyperMetroidRandomizerCLI/Hyper_Metroid_Rando_Base_ROM.sfc'
Download the latest unheadered Hyper Metroid ips file (as of this writing, 1.0)
Extract the ips file from the rar file using a local tool or extract.me
Apply the ips using Lunar IPS or a Web ROM patcher. Overwrite 'Hyper_Metroid_Rando_Base_ROM.sfc' with the outcome.
Apply 'PatchesCombined.ips', which was cloned from git, in the same way as step 5, overwriting the ROM.

The resulting checksum should be:

$ shasum ./Hyper_Metroid_Rando_Base_ROM.sfc
a033798b072c61ab55c32ecd0082652fa1a2f345  ./Hyper_Metroid_Rando_Base_ROM.sfc

Then to generate a randomized ROM,

dotnet run -- --difficulty Casual

difficulty can be Casual, Veteran, Masochist, or Max (Max is experimental, appeared to be commented out in the original rando)

Github info

This repo is shown as "17+N commits ahead, 17 commits behind" the original due to removal of a file from this fork's repo history. The 17 commits are otherwise actually identical between the repos, but unfortunately git considers these commits as divergent.

Important technique to know for Hyper Metroid randomizers: Angle Down (L by default) + Down while midair to instant morphball.

Rules:

  Unlock the 15 Gates to access Tourian and defeat Mother Brain
  Level design modified to prevent morph locks and increase item variety
  Walljumping is required
  Tourian Item may only be obtained after Baby Metroid trigger

Casual Difficulty

  All 100 Items are included
  Varia Suit does not spawn in Norfair / Lower Norfair
  Gravity Suit does not spawn in Maridia / Maridia Depths / Wrecked Ship (past Phantoon)
  Morphing Ball may only spawn in Crateria
  Better distribution on Energy Tanks to assist casual play
  Infinite Bomb Jump is not required (more frequent early space jump spawns)

Veteran Difficulty

  All 100 Items are included
  Experimental Difficulty:
        Gravity Suit may spawn wherever possible
        Varia Suit may not spawn in Lower Nofair
        Certain item combinations for hellruns / gravity suit hellruns may not be possible.
        Certain deep suitless underwater sections may not be possible without High Jump Boots and Springball.
        Morphing Ball may spawn in both Norfair and Crateria.
  Different algorithm for increased randomization
  Decreased frequency of Energy Tanks
  IBJ, midair springball jump, and other advanced techniques are required

An Item Randomizer program for the Super Metroid Romhack called Hyper Metroid.
It's a fork from Dessy's original Super Metroid Randomizer program, that can be found here: https://github.com/Dessyreqt/smrandomizer
