#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,
    };
