MultiworldGG vs Universal Pokémon Randomizer ZX

MultiworldGG is a multi-game randomizer that joins supported games in one multiplayer session. An item found in one player’s game can be assigned to another player, and supported games can also be generated as single-player experiences. The project is a fork of Archipelago, with tweaks and additional third-party worlds. Players can generate locally with the desktop client or use the website by uploading YAML configuration files or ZIP archives. Lobbies let participants upload configurations and coordinate in chat before a host generates the multiworld. Hosts can upload a generated ZIP or multidata file and provide trackers and patch-file downloads. Installations include a launcher, generator, server, and some clients; desktop downloads are available for Windows, Mac, and Linux. The website also links tools such as a text client, checklist tracker, and manual world client. Website-generated multiplayer games are limited to 30 players; larger games must be generated locally. Many catalog worlds are still in development and may be buggy or unfinished. MultiworldGG is free and open source.

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.
