Re: [hatari-devel] Re: Feature request: allow to specify "-d" with autostart

[ Thread Index | Date Index | More Archives ]


TT issue wasn't reproducible after recompiling Hatari
(I hate hasenbugs), so I commited --auto support (split
to several commits).

As using separate INF files content fixes several autostarting
issues, I commited that also, but several issues still remain
with autostarting:

It would be good if you could test autostarting your favorite
programs & demos.

That null in A0 is not bug, if you look at the function you see that
it is
explicitly set to 0 at $00e014e2. Don't ask me why, but they sometimes
the blitter like that. You will also see that the bus-error handler
was set to
an address inside the function to catch it. That function is called from
Blitmode(), to detect wether a blitter is present. Blitmode just
starts before
this function, at $00e014b4. Obviously the desktop tries to activate the
blitter there, according from the setting from desktop.inf.


Using DESKTOP.INF saved with TOS 1.04, got rid of crashes
with that TOS version after the autobooted program exits,
and it works fine with TOS 1.06 & 1.62.
-> Need to update Hatari desktop.inf

TOS 4.04 works otherwise with that, but comes up with
2-color 320x200 video mode!
-> probably need separate newdesk.inf for newer machines

TOS 2.06 still tries to access blitter regs with that on ST.

Saving NEWDESK.INF from TOS 2.06 under ST, verifying that
it has blitter disabled on STE, and modifying that to do
autoboot doesn't help.  It still tries to do halftone
regs addresses on ST after autoboot.   Seems very much
like TOS 2 bug.

PS. Something in my patch breaks TT emulation.
I don't see how that could happen, but I'm debugging...
