Windows Dev.7.2B

This version adds better breakpoint controls including data breakpoints (via the DB command). Type '?' in the command window to see all the commands so far. It also adds Alt-Number keyboard shortcuts to the 3 editable debugger windows (no need to tab all the time).

Windows Dev.7.2A

This release as a few very important bug fixes. First the editor corruption has hopefully been fixed. The debugger disassembler has been totally refactored to support the interactive disassembler that will be in version Dev.7.3.

Windows Dev.7.2

Lots of features on this one:

• LOAD directive - use to include another source file into the one that is being assembled (see etc/asm/hello.asm.
• The debugger's disassembly now shows labels generated from previous build.
• Added Ctrl-R to build & run your code. Requires opt start:<address> in your source for it to work.
• F4/Shift-F4 now cycles through the errors in the editor.
• Editor has a brand new status bar (shows cursor position and errors).
• Cut/Copy/Paste line has been added to editor.
• Debugger goto function now accepts full expressions including labels in previous build.
• F3/Shift-F3 implemented for memory dump to cycle through command window searches. Also searched values are highlighted in green.
• Added binary number support in assembler. Prefix used is %. For example, for the value 42, use %101010.
• Fixed lots of bugs in editor and assembler.

Windows version Dev.7.1

A quick patch that fixed a parsing bug with DB. But also added DW.

Version Dev.7

This release has the integrated assembler. The editor and assembler is quite basic for now. There are no macros and it only works for 48K.

Windows version Dev.6

A critical bug was fixed in this version that stopped some games and tools from working. The opcode

JR $7F

was causing a jump to -127 instead of +127. This was such a rare occurrence that none of the unit tests picked it up. Hopefully there isn't any other bugs in the Z80 emulation. Let me know if a game crashes on this emulator and doesn't crash on another.

Version Dev.5

Improved 128K support and Command Window. Added new window size (Ctrl+3).

Windows version Dev.4

This is version Dev.4 of Nx. Please read the README.md file on github.

Windows (Version Dev.1)

Version Dev.1 of the NX ZX Spectrum Next emulator.

Currently emulates 48K Spectrum without sound and contains basic debugger.
