It should ;)
But I think I understand precisely the problem now (in hatari, -Nn is passed as a negative argument to the function when the addressing mode is (Rn)-Nn, I'll have to rewrite it by adding a sign variable and keeping Nn unchanged).
Don't expec this fix before tuesday or wednesday (we'll have family at home in the next days).
At least, I see how to fix it definitively now.

Quick question Laurent - does the patch also work for (Rn)-Nn addressing?
If I keep my workaround just for this case and remove it for the (Rn)+Nn cases the remaining problem seems to go away...

Yep definitely something is slightly different on real HW. I'm getting selectively black pixels in Hatari where they look correct on HW. Previously I was getting a completely destroyed image.
It's going to take effort to figure out what's going on but I still see some kind of problem. I'll try to narrow it down a bit.

Perhaps I spoke too soon. There is something funny still happening - but I'll need to do more checks to make sure it's not my fault. I'll update soon when i have more info....

It works for me - everything looks good!
I'll report if I run into any problems with it but I don't think so..

underscore demo seems to crash now but it also crash with the n-1 version of hatari (ie without my patch).
There's a regression with this demo, it was at least working to the 4rth screen before.
I continue some tests but the patch seems OK to me.

Woo, that was quick. Thanks!
If the patch has made it into the repo, I can just collect tomorrow's
nightly build and see if that works for me. Sounds like it probably
will. Otherwise I'll try a local build tomorrow.
unfortunately, it seems builds at http://antarctica.no/~hatari/ are not regularly updated anymore (and it even returns a HTTP 503 error at the moment :( )
