tomcw 2258d01184 MB: SC01 is only mapped to the 6522 at Cn00 2021-03-28 22:16:34 +01:00
TomCh 96bbc0c435 Improve SSI263 (PR #939)
New class for SSI263 (2 instances per MB/Phasor card)

Switch from one-shot phoneme playback to ring-buffer
Use a new dedicated ring-buffer (distinct from the AY8910 ring buffer)
Gets rid of: SSI263Thread, the 2 events, and the 64 voices

Support the 2-bit Duration b7:6 of phoneme register for both SC01 & SSI263 (to fix #929)
Updated save-state
Updated IRQ logging (output cycle & 6522 source)

ThorstenB 4543117f81 More clean-up, portability and another debugger fix (PR #847)
Fixed debugger main "data" window behaviour:
. When activating the main data display ("data" command) the cursor keys wouldn't work until the minidump ("md1") was also enabled. NB. The cursor keys should work in the main data window, independently of whether the minidump is active.

TomCh 6125c2b12d Support for synchronous events (PR #841)
Switched Mockingboard/6522 Timer interrupts & Mousecard's VBlank interrupt to use synchronous events.

TomCh 769d4c6927 Support 2nd Disk][ card and improved card management (#726) (PR #741)
Support 2nd Disk][ in slot-5, via command line:
- -s5 diskii
- -s5d1 \<imagefile\>
- -s5d2 \<imagefile\>

NB. there's currently no Configuration UI support, except the Drive icons' tooltips show what's in slot-5 & slot-6 (for drive-n). So there's no way to eject the disks or insert new disks. The use-case I'm supporting it Wasteland which just has the 4 disks in the 4 drives.

Improved card management:
- Added `class Card` (in Card.h) which all other cards (that exist as classes) derive from (eg. LC,SSC,Mouse,Disk2).
- Added `class CardManager` (in CardManager.cpp\h) which now manages the 8 slots (and aux slot).
- Added `class Disk2CardManager` (in Disk2CardManager.cpp\h) which provides methods for operations that act on all Disk2 instances at the same time.
- Currently limited to just 1x SSC and 1x Mouse card (why would you need more?). This simplifies things, meaning there's no need to have dedicated SSCManager / MouseCardManager objects.
- Currently the 2nd Disk2 card can only be put into slot-5. This limitation is just due to the complexity of the Configuration UI. Having a more general drop-down per slot UI would remove this limitation.

TomCh d1b595f7bd Fix for "Mad Effect 1&2" demos (PR #725)
