-
- SOUND
-
- KEY SEQUENCE: None
-
- The SOUND MENU option allows you to turn A64's sound emulation on
- and off.
-
- The SOUND menu option has two settings: ON and OFF. You can
- select one or the other of these settings and selecting one
- automatically unselects the other. The current selected setting
- is shown by displaying a checkmark next to it.
-
- When ON is selected A64 will emulate the C64 SID chip.
-
- When OFF is selected A64 will ignore all functions related to
- sound. This will not keep C64 programs from running correctly.
- You just won't hear anything when the C64 program tries to make
- sound.

- CIA RATE
-
- KEY SEQUENCE: None
-
- The CIA RATE menu option will allow you to control the speed of
- C64 CIA based interrupts. To see what effect this option can
- have on C64 programs try the different setting and watch what
- happens to the cursor speed on the BASIC screen.
-
- The CIA RATE menu option has three settings: NORM, FAST and SLOW.
- You can select one of these settings and selecting one
- automatically unselects the others. The current selected setting
- is shown by displaying a checkmark next to it.
-
- When NORM is selected A64 will execute CIA based interrupts at
- their normal rate.
-
- When FAST is selected A64 will execute CIA based interrupts at
- twice their normal rate.
-
- When SLOW is selected A64 will execute CIA based interrupts at
- half their normal rate.
-
- NOTE: When running C64 telecommunications programs the CIA RATE
- menu option should be set to NORM.
