puts machine code inside BASIC loader. What assembler do that?

zasm, for instance.

I have Windows and I can't try.

I have released a version that includes shrinkler compressor, developped here.

So from a input binary file assembled with org $8000 you will have a compressed TAP file like this:

Has it been tested on real hardware (48k,128k,+3) Just curious because a lot of these loaders that perform seemingly fine in emulation have issues on the real thing.

I must confess I never really thought about a better loader than what zeus/pasmo gives you but fair play there appears to be scope for improvement over what the assemblers can give us. I am just concerned if it will work on real hardware.

Yes. It works on real hardware.

The program fails if you have an interface that moves the basic. A spectrum 48K with a betadisk interface moves the basic away from 23755. You should probably check PEEK 23635+256*PEEK 23636 in order to locate the start of your code.

If you need to know where your code is executing, i use this little trick:
