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
. 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.
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.
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.
1) Uthernet card now returns floating bus for slot ROM at $Cs00-CsFF (where s=3).
2) Fixed IoHandlerCardsIn() to not map in the card in slot3's slot ROM when SLOTC3ROM=0.
Also:
. moved the typedef 'iofunction' from common.h to memory.h
. 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
1.26.0.1
. NTSC video modes (TV Color, TV B&W, Monitor Color, Monitor B&W)
. Full Screen using native resolution (not 640x480)
NB. 6502 emulation is slower now, which means disk loading (ie. full-speed) is slower.
. EG. Aztec.dsk: from F2 boot to "Press any key". (Release build, 50% "TV Color", not run in VS, VAIO laptop)
~4 secs: AppleWin 1.25.0.3 (built with VS2005)
~7 secs: AppleWin 1.26.0.1 (built with VS2008 or VS015)
. means that disk accesses (eg. loading) is much quicker
Correct naming of video modes (in UI and code)
Pixel adjust for NTSC B&W and Color video modes to align with other video modes
Also:
. support new CpuType independently of Apple2Type
. save-state: don't save disk track image if no disk
. save-state: re-init AppleWin internals & UI to reflect changed Apple2Type
