Development Tools

Emulators

• CSpect emulates many features of the Next and includes an assembler.
• ZEsarUX aims to emulate all features of the Next and includes remote debugger support.

Assemblers

Any Z80 assembler can produce code suitable for the Next. However, the Next and most emulators cannot load raw blocks of Z80 code, so a Spectrum specific tool will be useful for creating .TZX or .TAP files with the necessary loaders.

• Zeus-ish provides a complete Z80 IDE and Macro assembler, plus an integrated Spectrum emulator. However, the emulator does not support all features of the next.
• SNasm is included with CSpect and is the only current assembler to support the Next extension opcodes.
• Pasmo is a long established Z80 assembler, but has been out of development for a long time and may not support the extension opcodes.

Compilers

• Z88dk is a C to Z80 compiler which is developing support for the Next. It includes an assembler that will accept the new ZX Next opcodes.
• ZX Basic is a Basic to Z80 compiler with extensions added to Sinclair Basic.
