There was a previous version of Gradius II pirated。Game Genie doesn't work too.

可能在 $5xxxxxxx的地址上和金手指卡的work ram有冲突。

或许这部分地址空间会被写用做寄存器设置,而金手指卡同样也在这里读写

Krzysiobal previous identified an issue with the Game Genie and carts that map anything below $8000, and like the original, this reimplementation of the FCG-2 puts its control registers in the $6000-$7FFF range.

But I can't see how that could pose a problem unless any Game Genie codes are entered...

I wonder what the MJ338986 are. I guess they have to be some kind of presettable down-counting IC ... maybe equivalent to 74'169s or '190s or '192s?
