Pulseman (originally known as Spark) is a platform game for the Sega Mega Drive/Genesis. It was only released as a physical cart in Japan, but was only available to North American gamers via the Sega Channel on Sega Genesis. The game was never sold in Europe.
It was developed by Game Freak, the development team that would later go on to produce the Pokémon series of games for Nintendo. Which explains the quality and engaging characters.
The cartridge is fresh and comes form new parts, so it may be tight going in and out of the console.
