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

• 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.
