SMZ3 Crossover Randomizer
What it is
SMZ3 Crossover Randomizer is a free web tool that combines Super Metroid and A Link to the Past by placing items from both games across locations in either one. Players move between games through certain doors and entrances, and the stated goal is to defeat Ganon and Mother Brain before finishing either game. Its logic-based placement checks whether locations can be reached with the progression items still available; the project also describes multiworld play, with items distributed among worlds. Settings cover goals, logic levels, item placement, entrance and enemy shuffling, and in-game hints. Super Metroid logic has Basic, Medium, Hard, and Custom levels. Accessibility choices can require every location to be reachable or only the locations needed to beat the game. Generated seeds have individual pages, and ROM patching occurs in the browser without uploading the ROM. Official presets can be browsed without an account, but saving personal presets requires sign-in. The site says the project is early in development and may sometimes be broken. English is the only available settings language, and some A Link to the Past randomization issues remain.

The verdict
