Why did Seibu decide to protect this game so heavily? You'd think the game they'd do this for would be Raiden II, instead.
I think after alotta their previous games were ripped off by the bootleggers for the first game on the new platform they just protected the shit outta of it using as much of the protection devices as they could.
Not that it worked in the end as there are some bootlegs of Seibu Cup Soccer that made it out.
