Olha que coisa interessante (Jogo raríssimo do Mega que só fui conhecer hoje):
[Sega Genesis/Megadrive] Outback Joey:
Western Technologies and published by HeartBeat Corporation. Specifically designed to utilize the fitness sensor-integrated Mega Drive peripheral HeartBeat Catalyst, it was released exclusively in the United States in November 1993 and only available as a pack-in with the either the HeartBeat Catalyst or the HeartBeat Personal Trainer; as the hardware only had a production run of 1,000 units total, it is assumed not many more copies of Outback Joey were produced as well. As such, both are considered some of the rarest pieces of Mega Drive history in existence.
Story
The titular protagonist Joey, a proud kangaroo and champion boxer, lives in the Outback of Northern Australia with his friends, family, and a love interest named Matilda. One day, a poaching expedition led by the evil gourmand Gustave McGullet captures Matilda and some of Joey's other friends, soon to become the blue plate special at McGullet's Greasy Spoon in Tasmania.
To save his friends, Joey must follow the poachers' trail and gather shards of a talisman to present as a tribute to the Indigenous Australian people so that they may guide him from one region to another. Undaunted by the many dangers that lie ahead, Joey sets out on his treacherous mission through the Australian Outback.
Gameplay
Outback Joey is a standard platform game with minor action platform elements. The titular Joey must traverse a series of four levels, and use his species' developed jumping ability to attack enemies with kicks and avoid obstacles. In certain areas, Joey can acquire boxing gloves and become a boxing kangaroo, making it easier to defeat enemies (as opposed to kicking or avoiding them). To finish levels, Joey must find all four pieces of a talisman and bring them to the end of a level. If the talisman is incomplete, the player must restart the current level from the beginning. Heath lost from enemies and obstacles can be regained by collecting energy drinks.
At the start of the game, the player must create a profile, and set how long their workout regimen will last for and a target heart rate. Joey's stamina is tied to the player's heart rate (as explained in the Hardware section below) - if the player's heart rate becomes too high or too low, Joey will become exhausted or lethargic, drastically reducing his movement speed and jump height until the player's heart rate returns to the defined range. If the player doesn't finish the game by the end of the designated timespan, the game automatically ends.
BlastEm emulator required
You'll need a new-ish nightly of BlastEm to play it, as it requires emulation of the HeartBeat Trainer peripheral. The peripheral controls are mapped to X/Y and Z/C on the six-button controller.
