Z80 Assembler software for Windows PC

I need to compile some Z80 code including zexdoc and zexall for testing my Z80 & CPM2.2 emulation(s).

I have used zmac a few years ago.
I have seen mention of WLA DX as being a good cross-assembler. However, I gather there are differences required in the source for this to work.

What are you using?
Advantages/disadvantages?

Personally, I use the environment prepared by Wayne Warthen and the ZSM assembler included there.

I switched to AZ80 and found it has none of the foibles of other cross assemblers, its well established, well supported, built on a solid base with reputable names in its credits: https://www.retrotechnology.com/restore/az80.html

Thanks for the info guys Smile

The main cross-assembler used seems to be called TASM32 (Telemark Assembler).
However I note there is mention of uz80as (Micro Z80 Assembler).

I have an old version of zexdoc.src and zexall.src and zmac will assemble this but there is a hex address disjoint where .DS n is used. This seems to be an issue with other assemblers too so I should probably just replace the DS usage.

I have a newer version zexall.sms.asm (zexall-sms-0.18) and this requires wla-dx to assemble. However there is no windows binary and the build instructions are foreign to me and require a lot of software to be downloaded to my windows pc. There is some sms (sega master system) specifics that I would need to remove. However, the macros seem to be better for the instructions, and the are apparently some fixes for the older zexall programs. zmac will not compile this though.

I am inclined to try TASM32 since Wayne uses it and I know ROMWBW is very popular. I will have to see what errors it throws on the versions of zexall.

I've used TASM32 too for all the Z80 related stuff.

You can download the last version 3.2 here: https://www.ticalc.org/archives/files/fileinfo/250/25051.htm l

Online manual (v3.1): http://www.cpcalive.com/docs/TASMMAN.HTM

I use it inside a Win XP VM...

Tried TASM32. It doesn't handle the macros used in zexall Sad

Found WLA DX windows exe version so going to download and try this next.

Tried wla dx but it didn't like the code I wanted to assemble. After a while at fixing the source I gave up and reverted to zmac. Zmac is working for me with this source.

Now have both zexall versions working. One compiles/assembles with ZMAC and the other with WLA, both under Windoze.
