Vale... Here it comes the useful stack backtrace, below my signature.
It seems "err = ti68k_init();" at gui/main.c:195 returns -1 for some reason and
that the error handling seg.faults when trying to call cable->close() because
cable is NULL.
Since I don't know the code I can only guess, but is this that the failure is
to early and the error handlers can't imagine anything going wrong prior to
cables getting a value? I'm attaching a patch that removed the SIGSEGV and
instead makes tiemu show a message box saying "tiemu : err: Msg: Transfer
aborted Cause: the user !". Which is better, but not really clear to me.
Tracing down why ti68k_init() returns error ends up at hw_init() in
core/ti_hw/hw.c which gets confused since img_infos.calc_type=='\0',
apperantly. Which is indeed what the Image information states in it's
output. "Calculator : nonCalculator : none".
So my guess is that the conversion of the OS download failed setting the
calculator type silently.
I removed the ROM image and tried starting tiemu against the OS
download, and guess what?! Now it works.
My guess is that you should probably apply the patch removing the sig11
and don't care about that the recent version can't work with old rom
converts. If you're really into working with this issue, maybe you
should think about a clearer error message than the above for a corrupt
ROM image.
For what it's worth skin changing doesn't work for me and having a us
keyboard mapping is very annoying, but those are other issues that I
might or might not file bugs about...
Thanks! Now I can forget my calculator at home without missing it too
much.
