  • -rot180 Rotate the display 180 degrees
  • -rot270 Rotate the display 270 degrees
  • Command line processing cleaned up a bit
  • cspec_win.dat file format changed. Now includes a version [0], and screen rotation [1]

Hello Mike
Thanks for the very useful emulator.
I found that the following instruction is not handled correctly by the emulator:

DD CB nn FF: set 7, (ix + nn), a

This is the undocumented opcode that allows changing bits at address (IX+nn), then copy the result to reg A.
I hope this will be fixed in future versions
Thank you!

I've followed the steps from https://specnext.dev/tutorials/creating-a-z80-assembly-development-environment-on-windows and used 'Next distribution 32Mb SD Card Image' for the mmc image.
After building the project.hex and putting it into the tbblue.mmc image, I run the command:

E:\SpectrumNext\project\bin\CSpect.exe -r -brk -w3 -zxnext -nextrom -map=project.map -mmc=E:\SpectrumNext\sdcard\tbblue.mmc

No window opens.

Instead, CSpect.exe slowly eats memory up to the 64GB and I have to kill it.

If I use the same command without the -mmc=E:\SpectrumNext\sdcard\tbblue.mmc

I get the green screen with the copyright message at the bottom.
Nothing more happens but the program still appears to be slowly eating the RAM (about 24KB/s)

hi Mike, you wrote a Key map to use the emulator with Windows PC! symbol shift, caps shift, graphic mode etc. I thank you.
