tomcw f03f5e0904 Fix for 6522 counter underflows falsely delaying when IRQ occurs. (Fixes #1176) 2023-02-05 11:02:56 +00:00
tomcw b519031de4 WM_CREATE: call CpuCreateCriticalSection() instead of CpuInitialize() 2022-02-12 19:11:34 +00:00
tomcw 3fe06faf65 MB/6522: remove the legacy g_nMBTimerDevice variable.
Fix ASSERT from previous commit as SY6522.Reset() needs CriticalSection.

Split 6522 out of MB code and into own class (PR #1028)
NB. Update CpuInitialize() & CriticalSection creation:
. call CpuInitialize() on WM_CREATE to create CriticalSection
. needed as MB_Initialize() needs CriticalSection

Debugger: Add IRQ support to LBR and new command to Break on Interrupt (#987, PR #990)
Extend LBR so that it includes the control-flow on a taken interrupt
Add a new command 'brkint <0|1>' to support Break on Interrupt

Internal: in core emulation loop, moved IRQ/NMI check to start of loop so that just the "interrupt vectoring" case can be single-stepped (instead of previously opcode + interrupt vector).

Debugger help chm: update Breakpoints section to include BRK, BRKOP and BRKINT

Ensure all header files can be included (in any order) after stdafx.h. (PR #866) 2020-11-11 21:15:27 +00:00

Support for synchronous events (PR #841)
Switched Mockingboard/6522 Timer interrupts & Mousecard's VBlank interrupt to use synchronous events.
This is a linked-list of ordered timer-based event, where only the head of the list needs updating after every opcode.

Removed 65d02 and used the regular 65c02/6502 headers instead (PR #825)
Removed 65d02.h and reconstructed this code using a combination of existing 6502.h/65c02.h and extra C Pre-Processor macros to include (or omit) the extra heatmap functionality.

We still end up with a normal 65c02 instance and also a debug 65c02 instance, but both will derive from the same 65c02.h file (+ same for the 6502 normal/debug instances).

Also:
. Added cpu_heatmap.inl for the built-in debugger's read/write operations.
. Support CpuRead/Write() from Z80 to hook the heatmap r/w.

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.

tomcw 7d38b1ba38 CPU save-state: added 'Defer IRQ By 1 Opcode' (v5) and comments for why the other state doesn't need saving 2019-11-18 15:08:59 +00:00
tomcw 9ee9414bb6 Debugger: show video-scanner's h,v position (at the expense of losing 2 watches). (#666) 2019-09-21 16:37:45 +01:00

tomcw ceb0416bf3 Fixed 6522 & interrupt:
. Broadside needs to see IRQ within 17 cycles (6 opcodes) of 6522 counter underflowing to detect Mockingboard. (Fixes #605)
