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.
- Provides a complete Z80 IDE and Macro assembler, scripted disassember plus an integrated Z80 emulator for a range of machines including partial Next support
- Supports the Next opcodes directly
- Supports remote debugging on the Next using ParaSys across a serial link
- Supports MMU paging in the integrated emulator
- Supports sprites (core versions prior to 2.00.26) in the integrated emulator
- A long established Z80 assembler, but has been out of development for a long time
- Supports all currently known Next extension opcodes through this modified Pasmo from Russ McNulty and Tony Thompson and also now supports outputting .sna files to use with CSpect, thanks to Russ McNulty
Included with the #CSpect emulator
- Supports the Next extension opcodes directly
Part of Z88dk
- Supports the Next extension opcodes directly, linking assembler with large z80 library, targets any memory configuration
- Supports all (core2.00.28) Next extension opcodes, ZXN memory model (8 memory slots with 8ki pages and 1.75MiB virtual device memory), SAVENEX to build NEX files directly from ASM source and it is under active development (feedback is welcome).
- Open source project ("BSD-3-Clause" license), windows executables available at releases, mac and linux users are expected to simply build from source (both make and CMake are supported).
