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
New class for SSI263 (2 instances per MB/Phasor card)
- support 2nd SSI263 at $Cn20 connected to 6522-A (at $Cn00)
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)
. class hierarchy: WinVideo IS_A Video (ie. WinVideo is a subclass of Video)
. GetVideo() singleton instance of WinVideo in AppleWin.cpp, exposed via Interface.h
. Split AppleWin -> Core with the functionality really needed by the emulator.
. Split AppleWin -> Utilities for generic code not called by other emulator components.
. Split AppleWin -> CmdLine for the command line option parsing.
And fix two general issues:
- confusing behavior when entering the builtin (mini) assembler mode,
- and also fixes the "cl" (clear flag) command - which was documented, but did not work at all (due to an "interesting" command/syntax conflict...).
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.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.
. Improved DEVICE_SELECT' I/O support (including Echo+).
. SSI263_Read() only for Phasor in Phasor mode.
. save-state: v6 (Phasor unit): phasor mode extended.
SSI263 (MB/Phasor) bug fix for when RESET/Power-cycle during phoneme playback.
Logging:
. improved for SSI263
. in CPU.cpp, added 'IRQ' / 'ISR-end'
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.
. 6502 interrupt delays 1 opcode when interrupt occurs on last cycle of opcode (#724).
. Only 1-cycle delay for VF_TEXT & VF_MIXED mode changes (#656).
NB. Mad Effect 1 still has a bit of flicker on Space Invader (left edge)
Changes to ease code compilation in GCC.
Disk_t and HDD contain a std::string and for this reason they need a proper constructor, ZeroMemory is not guaranteed to work.
. Move the BRK and invalid opcodes checks out of main emulation's Fetch() and into DebugContinueStepping()
. Added a new break condition: when PC reads floating bus or I/O memory
. On a break condition, output a 'Stop Reason' message to the console
. Debug 'G(o)' cmd now defaults to normal speed (and precise video updates)
. New debug 'GG' cmd enables full speed (and periodic video updates)
. Single-stepping (normal or full speed) now routed through ContinueExecution()
. Removed Cpu6502()/Cpu65C02() check for debug breakpoints
. Removed the (undocumented) SHIFT+F7 feature to exit debugger for 'normal speed breakpoints'
. Removed the g_bDebugNormalSpeedBreakpoints variable
. Removed NTSC_VideoVbl(), since it's not accurate during full-speed. (Nothing was using it)
. Renamed VideoGetVbl() to VideoGetVblBar()
. Correctly pass Vbl (not VblBar) to Mouse's SetVBlank()
Fixed JoyUpdateButtonLatch() to debounce in 5mecs instead of 5secs!
SpkrToggle() was using redundant global ('cyclenum') when using the PC speaker.
. I reworked the code (as it looked out-of-date),
but probably better to just remove all the PC speaker support.
