The Ocarina of Time Randomizer, available at ootrandomizer.com, has become one of the most active competitive ROM hack communities for any N64 game. Every chest, song, shop item, skull token reward, and NPC gift is shuffled to a random location, and the challenge is to determine what items you have and how to route efficiently to Ganondorf.
The settings system is extremely deep. Seeds can be configured to include only major dungeons, extend randomization to overworld items, and modify the logic to require specific speedrunning glitches. Weekly races on Racetime.gg attract hundreds of participants.
The randomizer supports both the N64 ROM and direct 3DS CIA installation. A companion tracker tool helps players keep track of available items without spoiling locations.
