Here ya go. This is also at:

I set up a win11 vm and discovered it's quite a pain to get the full
MSYS2 environment set up so that you can run "make" and "git" commands,
and even after getting it all working, still it's not 100% because co2ba
isn't working even though it's running in a suitable version of bash.
So "make clean all" or "make clean M10eu" fails when it tries to
generate the .DO loader.
So this is a minimal & manual setup where you only install z88dk itself
and you download the dl2 repo as a zip file instead of git clone.
To update you'll have to manually download new zips and unpack them over
the exiting dirs, since you can't just run "git pull" to update.
You have to run z80asm commands directly, including setting all the
commandline flags.
You have to manually "del *.o *.bin *.CO" before every z80asm command
because it won't overwrite the old files and you'll wonder why the
binary isn't changing or working...
But it's the minimal steps to get going.
================================================================================
Download these in a browser:
http://nightly.z88dk.org/z88dk-win32-latest.zip
https://github.com/bkw777/dl2/archive/refs/heads/master.zip
Extract the downloads in a CMD window in your users home dir:
Search > cmd > Open
C:\Users\bkw>tar xvf Downloads\z88dk-win32-latest.zip
C:\Users\bkw>tar xvf Downloads\dl2-master.zip
C:\Users\bkw>ren dl2-master dl2
C:\Users\bkw>exit
Set up z88dk environment variables:
Search > env > "Edit environment variables for your account"
In the top box "User variables for bkw":
* select "Path" > Edit... > New > %USERPROFILE%\z88dk\bin > Enter > Ok
* New...
Variable name: ZCCCFG
Variable value: %USERPROFILE\z88dk\lib\config
OK
OK
DONE WITH SETUP
You should now be able to open a new cmd window and run "z80asm" with no
arguments and it should run and display the version.
============================================================================
Now building TEENY, the baseline command is
z80asm -m8085_strict -no-synth <options...> -b TEENY.S85
"-m8085_strict -no-synth" is required every time
<options...> are one or more of
-DMODEL_x x= 100na 200na NECna K85na M10na M10eu
-DHIMEM=n use to generate .CO just below custom HIMEM
-DBAUD=n Only use if you have a FB-100 hardwired for 9600
-DDSR advised if you have a proper serial cable
-DERRCODES slightly more informative error messages
-DROM must use if running from rom
-DORG=n alternative to HIMEM, overrides HIMEM
-DPRGLEN=n required to generate valid .CO with CO header
You must always manually delete leftover object files from previous
builds before each z80asm command.
z80asm will not overwrite them and you will wonder why the binary isn't
changing.
del *.o *.bin *.CO

2-step process, build once without PRGLEN to find out the generated length,
then build again with PRGLEN to generate the final usable .CO:

Brian,
the TEENY ROM version you made does the job so far. Thanks for this. Not
100% sure,
but it seems BASIC has to be started before 1st use of ROM TEENY. I´ve
to investigate further.
Attached M10INT ROM file includes this version and I made the PIMngr
menu a bit nicer
One question I still have: How to build TEENY files on a WIN11 computer?
I´ve unpacked the z88dk-win32-2.4.zip and got ~500MB of data, not sure
if this amount is necessary to build the files.
Thanks again for your great work
Georg

It would be great to get a ROM version of TEENY at address
0x7CFB.
Attached since it's small.
Note this is the latest version an so not as well tested. I think
it's all working but I have definitely moved things around and made
changes so it should be considered a testing version.
I can help you get a build environment set up so you can hack on it
yourself if you want. Without resorting to WSL2 just to be clear!
There are native windows binaries for all the pieces, just needs a
little putting together.
