#CSpect 2.12.17

Another day, another version. This one for some devs who are trying to use the 1bit tilemaps, and another minor update for plugin writers.

#CSpect V2.12.17 changes

• 1Bit tilemaps now use Global Transparency for it's transparency, not the tile index
• Have added GetSprite() and SetSprite() to iCSpect interface for plugin writers

Download: #CSpect V2.12.17 Emulator

#CSpect V2.12.16

Another very minor update for plugin writers. This gives access to sprite image memory, and undoes a "fix" that wasn't right....

#CSpect V2.12.16 changes

• Reverted .NEX border colour palette change, was just wrong.
• Added PeekSprite(address) and PokeSprite(address,value) to iCSpect interface for plugins

#CSpect V2.12.15

This release is specifically to add to the plugin API, allowing plugin devs to control the debugger including single stepping and break points.

#CSpect V2.12.15 changes

• Plugin API TICK() now called while in debugger mode
• Plugin API can now control the debugger using the new extended eDebugCommand enum
• -remote command line switch added, to disable the "visible" part of the debugger

public enum eDebugCommand
    {
        none = 0,
        ///Set remote mode - enables/disables debugger screen (0 for enable, 1 for disable)
        SetRemote,
        /// Get the debug state (in debugger or not - returns 0 or 1)
        GetState,
        /// Enter debugger
        Enter,
        /// Exit debugger and run (only in debug mode)
        Run,
        /// Single step (only in debug mode)
        Step,
        /// Step over (only in debug mode)
        StepOver,
        /// Set a breakpoint [0 to 65535]
        SetBreakpoint,
        /// Clear a breakpoint [0 to 65535]
        ClearBreakpoint,
        /// Get a breakpoint [0 to 65535], returns 0 or 1 for being set
        GetBreakpoint,
        /// Set a breakpoint in physical memory[0 to 0x1FFFFF]
        SetPhysicalBreakpoint,
        /// Clear a breakpoint in physical memory[0 to 0x1FFFFF]
        ClearPhysicalBreakpoint,
        /// Get a breakpoint in physical memory[0 to 0x1FFFFF], returns 0 or 1 for being set
        GetPhysicalBreakpoint,
        /// Set a breakpoint on CPU READING of a memory location[0 to 65535]
        SetReadBreakpoint,
        /// Clear a READ breakpoint [0 to 65535]
        ClearReadBreakpoint,
        /// Get a READ breakpoint [0 to 65535], returns 0 or 1 for being set
        GetReadBreakpoint,
        /// Set a breakpoint on CPU WRITING of a memory location[0 to 65535]
        SetWriteBreakpoint,
        /// Clear a WRITE breakpoint [0 to 65535]
        ClearWriteBreakpoint,
        /// Get a WRITE breakpoint [0 to 65535], returns 0 or 1 for being set
        GetWriteBreakpoint,
    };

#CSpect V2.12.9

Been a while since the last update. This one adds the 2 new Next Registers that are required for the very latest NextOS - which is the main reason for doing this. There are a lot of other fixes as well....


#CSpect V2.12.9 changes

• 50hz/60hz bit now set in NextReg 5
• -debug added to the command line. You can now "start" in the debugger.
• Minor Fix to 60Hz audio
• Fixed AY partial port decoding
• Fixed a minor reset stall when it was waiting on a HALT before the reset
• NextReg 0x8c added
• NextReg 0x8e added
• Added AltRom1 support
• Fixed a serial port "send" bug. Now sends the whole byte
• Fixed tile attribute byte bit 7 - top bit of palette offset was being ignored
• Fixed esxDOS date/time function (M_GETDATE $8E)
• NEX file 1.3 now parsed... should load more things
• NEX files get IRQs switched off when loaded (as per machine)
• Fixed esxDOS date is wrong
• Fixed Border colour now sets the palette entry as well
• Fixed GetRegister() in plugins not working
• Fixed Copper run then loop not working
• Fixed Top line (in 256 pixel high view) is missing
• Fixed DI followed by HALT should stop the CPU
• Fixed Hires tilemap has clipping on far right
• F8 not steps over conditional jumps and branches that go backwards. Branches forwards are taken
• Fixed ADD HL/DE/BC,A no longer affects flags
• Fixed OUTI so that B is decemented first. (OTIR was already like that)
• Minor change to 60hz audio
• NextReg 0x69 can now be read
• DMA Continue mode added
• Fixed a timing issue with DMA, so timing much better

#CSpect V2.12.5

Fixed plugin loading. This was due to the new loading/reset system that was nuking loaded plugin mappings.
I've also added a "Tick" to the plugin interface which gets called once per emulated frame, along with a debugger call which allows you to tell CSpect to enter the debugger. This is handy if you need to debug the operation that "just" happened.
Lastly... I've included a very simple plugin example, along with the interface .CS files to look at.


#CSpect V2.12.4 changes

• Border now comes from fallback colour if paper/ink mode is 255 (as per hardware)
• Fixed Plugin loading. Was broken due to new system loading+resetting.
• Added new "Tick" to iPlugin interface, called once per emulated frame
• Added Debugger() call to CSpect interface, allowing you to enter the debugger from the emulator
• Added Plugin example (and current interface)
