Hollow Knight MultiWorld vs Universal Pokémon Randomizer ZX

Hollow Knight MultiWorld is a free, open-source set of add-ons for Hollow Knight Randomizer 4.0. MultiWorld distributes randomized items across linked game files for cooperative play, while the separate ItemSync add-on shares randomized pickups among players in a room. Players can use local randomizer mods, keep their own randomizer settings, choose nicknames shown when their items are collected elsewhere, and coordinate through a room code. The server assigns a random identifier to each randomization, allowing multiple sessions to run at once. Players can save, reload, reconnect, and rejoin to recover MultiWorld data after a crash before their first save. Mods are available through Scarab, which installs dependencies. Documentation lists a public server and explains local hosting with MultiWorldServer.exe; WAN access requires forwarding port 38281. The project supports Windows, offers advanced customization, seed sharing, and multiworld support, and is licensed under LGPL-2.1. Detailed spoiler logs are planned.

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.
