What SMZ3 Crossover Randomizer is

SMZ3 Crossover Randomizer is a free web tool that places items from Super Metroid and A Link to the Past across locations in either game. Players travel between the games through certain doors and entrances; the stated goal is to defeat both Ganon and Mother Brain, then finish either game. Logic-based placement checks whether locations can be reached with remaining progression items, and the project describes multiworld play with items distributed across worlds. Settings include goals, item placement, entrance and enemy shuffling, hints, and logic difficulty. Super Metroid logic offers Basic, Medium, Hard, and Custom levels. Accessibility options can require all item locations to be reachable or only those needed to beat the games. Seed pages show settings and allow browser-based ROM patching without uploading the ROM. Official presets can be browsed without an account, but saving and managing personal presets requires sign-in. The site says the tool is in early development and may sometimes be broken. Some A Link to the Past boss and enemy randomization issues remain, and entrance logic is not fully developed. Settings are currently English-only.
