CSpect 1.18

Changes to the debugger. This allows you set breakpoints using the physical address, allowing you to set breakpoints in code not yet paged in. This allows for simpler debugging of proper overlay code.
Also, if your using another assembler, you can use the new -16bit command line to use logical addresses only.

CSpect changes

• added -16bit to use only the logical address of the MAP file
• Execution Breakpoints are now set in physical address space. A HEX number or SHIFT+F9 will set a logical address breakpoint. This means you can now set breakpoints on code that is not banked in yet.
• Next mode enabled when loading a .NEX file

CSpect 1.17.1

Minor update to SNasm. 48K SNAs weren't saving out correctly, and labels under $8000 were whacky. This is now fixed.

SNasm changes

• Fixed labels
• Fixed SNA saving

CSpect V1.17

New version  of CSpect and SNasm with some big changes for those using it to dev. You can now specify segments and save out NEX format packages, allowing you to build "large" packages all from within SNasm.
CSpect will now load the new symbol format and correctly display the proper symbol when that bank is paged in, allowing overlays to work more seamlessly.

CSpect changes

• ULA colours updated to match new core colours. Bright Magenta no longer transparent by default. Now matches with $E7 (not $E3)
• Fixed debugger bug where "0" is just left blank
• New MAP format allowing overlays mapped in. Labels in the debugger are now based on physical addresses depending on the MMU
• You can now specify a bank+offset in the debuggers memory view (M $00:$0000) to display physical addresses. 
• Numeric Keypad added for debugger use.
• EQUates are no longer displayed in the debugger, only addresses. This makes the view much cleaner

SNasm changes

• SEG command added for Segment control on ZX Spectrum Next machines. Banks are 8K in size.
                                  SEG  NAME,BANK:OFFSET,TARGET_PC ; to create
  
                                  SEG  NAME              ;to use
  
• SAVENEX "name",StartPC,[StackSP] added.
• New MAP format exported for CSpect

CSpect V1.16

Okay, so the last version was actually a debug version and so some folk had problems running it. This is a proper release build. There are a couple of additions...

CSpect changes

• Fixed sprite transparency to use the index before the palette and colour conversion is done
• -r on the command line will now allow CSpect to remember the window location, so if you move it somewhere, it'll start up there again next time. Just delete the cspect.dat file to reset.

CSpect V1.15

There's been a few folk requesting an updated version so even though it's not a huge change, here it is...


CSpect changes

• Fixed sprite transparancy index. now reads transparancy colour from sprite palette.
• Timex Hi-Colour mode fixed
• M_GETDATE added to esxDOS emulation (MSDOS format)
  

M_GETDATE 
BC = DATE

DE = TIME

Bits Description

0-4     Day of the month (1–31)

5-8     Month (1 = January, 2 = February, and so on)

9-15    Year offset from 1980 (add 1980 to get actual year)

Bits    Description

0-4     Second divided by 2

CSpect 1.14

CSpect changes

• -joy to disable DirectInput gamepads
• Re-added OUTINB instruction (16Ts)
• Fixed a but with MMU1 mapping when reading, it was reading using MMU0 instead.
  
• In ZXNext mode, if you have RAM paged in MMU0, then RST8 will be called, and esxDOS not simulated
• Palette control registers are now readable (Hires Pawn demo now works)
• Reg 0 now returns 10 as Machine ID
• Reg 1 now returns 0x1A as core version (1.10)
• Layer2 transparancy now checks the final colour, not the index
• Fixed sprites in the right border area (the 320x192 picture demo)
• Timex Hires colours now correct (Pawn demo)

SNASM
