Ocarina of Time Randomizer vs Universal Pokémon Randomizer ZX

Ocarina of Time Randomizer changes where items appear in The Legend of Zelda: Ocarina of Time, creating a different playthrough. Its logic is designed to make every seed completable without glitches and avoid softlocks, even with any possible dungeon-key use. Players can adjust item and entrance placement, pots, crates, cows, shop prices, songs, cosmetic settings, starting inventory, and damage settings. The web generator lets users choose options, generate a seed, and patch a ROM in the browser. Generating and playing a seed requires an Ocarina of Time 1.0 NTSC-U or NTSC-J ROM. The site recommends a multicore CPU, at least 1.5 GB of RAM, and an updated browser. Mobile patching is supported but slower; listed device support includes Android phones with 2 GB or more of RAM and iPhone 5 or newer running iOS 10. Offline builds are available for Windows, macOS, and Linux. The project is free and open source. Its site points users to racetime.gg for races and Discord for discussion and help.

Universal Pokémon Randomizer ZX is a desktop tool for randomizing Pokémon game files. It is a fork of the Universal Pokemon Randomizer with added features and support for more games, including 3DS titles. Settings can change Pokémon base statistics, evolutions, wild Pokémon, moves, and movesets. The tool supports Windows, macOS, and Linux/Unix, and the release page provides a ZIP package to extract and launch with platform-specific scripts. It requires 64-bit Java 8 or higher; documentation says it needs at least 4 GB of memory when Java's memory setting would otherwise limit it below that. For 3DS games, it accepts decrypted CCI, CIA, and CXI formats. Randomized 3DS output can be a CXI file or a LayeredFS directory, usable with an emulator or a 3DS with custom firmware. A command-line mode accepts input ROM, output ROM, and settings-file arguments, with optional LayeredFS output and log generation. The software is free, with source available under GPL-3.0. Maintainers direct bug reports and help requests to GitHub issues and do not accept feature requests.
