How to Play Derby Stallion 64
Quick start
Begin with a ranch and review the horses available to you. Focus on one horse's preparation and race entry before expanding your breeding plans. Watch the result, then return to management and reconsider the next step. For a first session, learn that cycle before attempting Breeders Battle with imported ranch data.
Controls
Make decisions through the ranch and racing menus: choose the horse and the management action, review the choice and follow the on-screen prompts. In Breeders Battle, players take turns operating their ranches, with handover at the calendar screen; their horses compete by entering the same race.
Derby Stallion 64 — About this game
The race is the outcome of work done at the ranch. You own, breed and train horses, building a racing operation through decisions made between race days. Buying horses at auction offers another route to a contender. The Nintendo 64 edition also has Breeders Battle, which places participating ranches on the same timeline so their horses can enter the same races. The appeal lies in developing horses over time and comparing the results, with breeding and preparation shaping what happens on race day.
