This is the Game Gear software "Heavyweight Champ." The box and instruction manual are not included; only the cartridge is for sale. It cannot be read on Retro Freak, so please play it on the actual hardware. I believe it should work fine as it was playable on the Game Gear console back then, but please note that I have not confirmed its operation at the time of listing. This is an arranged port of Sega's arcade boxing game for the Game Gear. It's a side-view boxing game where you earn points by winning matches, and you can use those points to improve your stats. The original arcade version is from 1976, and it's said to be the world's first fighting game. ▲▼▲▼▲▼ Please Read Carefully ▲▼▲▼▲▼ ※ Instant purchase is OK.
