Timers #3

Closed jotego closed 7 years ago

In version v0.1 Timer B takes 1/2 of the time it should. According to YM2608 documentation is correct but Ghouls'n Ghosts has accelerated music because of this. If I add one more bit to timer B, GnG sounds correct.

How about Timer A? Check with real hardware/emulators...

Duplicated the count of both timers. Seems fine now in GnG and Castlevania.
