gollop's Randomizer can be found in the
Metroid Prime Randomizer Discord pinned in #corruption-general
In addition, you can also use MrMiguel's MP3 Updates that incorporate a bunch of bug fixees and quality of life improvements
The randomizer is subject to change once development for Prime 3 has begun on Open Prime Rando.
Category Rules
Using MrMiguel's MP3 Updates, by default, is not mandatory. However, every runner must be using the same release of it if they choose to do so.
Timing starts after selecting the difficulty.
Beat the game: Timing stops once you have entered a cutscene, elevator, portal, or teleport that will lead to the credits or Mission Final screen without any further game input.
Miscellaneous
The only permitted emulator is Dolphin, running on version 5.0 or later. Running the ISO on console via a USB Loader is allowed. "Speed Up Disc Transfer Rate" on Dolphin is allowed, to match loading times for USB loaders (this can be overridden by a category rule).
ISO inspection/ROM inspection/memory inspection/software reverse-engineering that determines item locations or elevator/teleporter destinations of the race seed prior to or during the race is banned. Save states, fast forward and disabling fog are banned.
Turbo controller functions are banned. However, these functions may be allowed if all racers permit it, or a category rule permits it.
