This was my first attempt at a website that I created a few years ago. It is basically a "getting started" guide for people who want to try out the Kingdom Hearts 2 randomizer. While it was my first website, I think I did a lot of cool things with it and am still quite proud of the work I put into it. Unfortunately, I have not kept up with the randomizer for the last couple years, so it is hopelessly out of date at this point. That said, a lot of the details (where checks are located, general strategies, etc.) still apply. This website is currently hosted on my GitLab, and can be found at https://kh2fm-rando-reports.com/! If you happen to be interested about the randomizer itself, it appears info on the modern version can be found here.
This is an eleventy project that is used to generate a static site that explains tips and tricks about the Kingdom Hearts 2 Final Mix Randomizer. The site lists locations of chests, describes other checks that could be important, and offers a few tricks for getting around some of the more difficult situations. The site is currently in early phases and will be updated to reflect that. The site is currently not live but should be soon.
The KH2FM Randomizer was created by Valaxor and can be found here. That website will generate a .pnach file that can be used with the Garden of Assemblage Mod in the PCSX2 emulator.
This mod was created by sonicshadowsilver2 and more info about it can be found here. The mod essentially creates a new hub-world that allows Sora to access the different worlds in the game in any order and without use of the Gummi Ship.
There are several guides that will help you get started with the randomizer. I recommend taking a look at the ones listed at the Discord. Some parts of the process change often, so it's best to follow one of the maintained guides listed there.
