This game originated in the arcade and was ported to nearly every imaginable system in the late 80's and early 90's. Seriously, the Lynx, 2600, 7800, GB, NES, Master System, and Game Gear all had ports of it! The two lead characters were featured on the NES's pack-in game, Super Spike V'Ball. There were an additional two sequels on the NES and the series was recently revived as a downloadable game for the PS3 and 360.
I guess what I'm saying is, this is nowhere near an obscure title.
It's just an obscure port.
