Hatari does have that feature.  It's implemented by
the "hatari-prg-args.sh" script.

Setting arguments requires modifying the program
basepage contents.  The script does it using Hatari
debugger and couple of chained, conditional breakpoints.


Or did you mean doing that in the in the Hatari itself?

That would require:
* options.c: option for command line content, verifying
  that it fits to basepage [1] + documentation
* Code that makes sure command line args are there only for
  the autobooted program, not for later programs, and it
  being available for the autobooted program also after reboot
* Storing that date somewhere in emulated memory space,
  probably somewhere in cartridge memory area
* cart_asm.s: if that data exists, copying it to basepage
  gotten one from TOS, before doing Pexec

If Nicolas or Thomas are interested to update the m68k
cartridge code for this, I can look to the rest.

[1] = 127 bytes.  ARGV can support more, but handling
that from the emulator side would be quite a bit more
ickier.
