Spec score 7.1 #18 of 24 in Game Randomizer Tools

What it is

SMZ3 Crossover Randomizer is a free web randomizer that combines Super Metroid with A Link to the Past. It places items from either game across locations in both games, with travel through selected doors and entrances. The stated objective is to defeat Ganon and Mother Brain, then complete either game. Logic-based placement checks whether locations are reachable with the progression items available, and the project describes multiworld play with items distributed across worlds. Settings cover goals, item placement, entrance and enemy shuffling, hints, and accessibility. Super Metroid logic offers Basic, Medium, Hard, and Custom levels. Accessibility can require every location to be reachable or only locations needed for victory. Seeds have individual pages showing settings; ROM patching runs in the browser without uploading the ROM. Official presets are viewable without an account, while saving personal presets requires sign-in. The site is in early development, may break, and reports unfinished entrance logic plus remaining A Link to the Past randomization issues.
