Ganbare Ginkun, which translates to "Do Your Best, Ginkun," is an arcade game. While specific details about its release date and developer are scarce, the "Imperfect GFX" note suggests a potentially early version or a bootleg of the game that may have graphical issues.  Further research into Japanese arcade game history would be needed to provide more detailed information about the gameplay and its place in the arcade scene.
