The hardware protection Seibu was using for some of their 1990s era games is all the more impressive that it has lasted longer to this day in still making a few of the Seibu games not yet fully playable. Have to give Seibu credit that their 1990s era hardware protection worked very well in preventing bootlegs from appearing back then.

If looking back about 8 to 9 years earlier, it was impressive that a whole bunch of Seibu pcb owners were working with Kale and Kale's test patches that were written to see how Seibu pcbs were running. A lot of work back then to get a lot of the hardware documented. Crossing fingers that there won't be a need to do that stuff again with remaining 1990s era Seibu games.

iirc years earlier someone had jokingly stated Seibu protected some of their earlier 1990s era games so well that they accidentally locked themselves out of the house. :-) It was likely either RB or OG that said that quote. Maybe why fewer functions were used when the newer games were released.
