Development Tools

Emulators

• CSpect

Emulates many features of the Next and includes an assembler

• ZEsarUX

A full feature emulator including a debugger - frequently updated to support Next updates

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

The emulator does not support all features of the next

• Pasmo

A long established Z80 assembler, but has been out of development for a long time

Supports most of the Next extension opcodes through macros from Russ McNulty

• SNasm - included with the CSpect emulator

Supports the Next extension opcodes directly

• z80asm - part of Z88dk

Support for the Next is being developewd

Compilers

• sccz80 - part of Z88dk

"sccz80 is derived from small c but has seen much development to the point that it is nearly c90 compliant"

Support for the Next is being developed

• ZX Basic

"a fully featured assembler / linker / librarian implementing sections"

A Basic to Z80 compiler with extensions added to Sinclair Basic.
