a1261e8339 Optimization to avoid recalculating DOC frequencies when APU value does not change 2023-06-18 00:12:53 -05:00

bdb4006e22 APU fixed 
* Fixed type that caused triangle linear counter to be ignored
 * Changed sweep to shift the current period, not the register value
 * Moved muting logic early to avoid setting DOC registers when not needed
