Here is a disassembly of Gunfright for zasm assembler which will assemble to a .tap file
The Skoolkit html output for the resulting .tap file can be found here.
There are also some BBEdit Applescripts in the archive folder that I use to convert the Hex Dump and Disassembler output from ZX Preview (also here) into source code that can be assembled in zasm as well as a hex dump perl script that I use to ensure that the disassembled source has not introduced errors into the .tap file compared to the original hex dump code.
zasm assembler is available here
