And another thing is that I want some kind of signing for them (like there's
for binary packages coming from distribution repositories)... Otherwise
in theory somebody could just have replaced them in the intervening years,
if that www-site was cracked in the meanwhile, or some malicious
intermediate http-proxy could be giving wrong binaries.

Before running it, does your version have same checksums as the version
I just downloaded:
$ md5sum Steem.exe steemupdate.exe unzipd32.dll
7d89731bd2bade75cf973ccd308ed50f Steem.exe
259d0340504a80fdcb2371367c3e704f steemupdate.exe
aaddb5561976f09c2d002d8ebc78d54d unzipd32.dll
?

Potentially true. Has somebody on the list tested this both on OSX &
Windows? :-)

With the all-in-one installer, there aren't any extra deps, everything
needed should be installed in one go, from one place.

I mean, I have some doubts about it working. Has somebody successfully
mixed C++ Qt & Objective-C Cocoa widgets in same program and succefully
built & run it?

While the SDL debugger UI would be bound by the Hatari screen size, it
doesn't mean that the output would have to be scaled like the Atari screen
is. Adding --desktop option support for ST mode too and running in
fullscreen would guarantee largest possible resolution.

If Hatari would be running at e.g. 1280x1024, you could fit several hex/asm
dumps on same screen... How many of them you typically and at maximum would
want to compare at the same time ?
(With single window approach it might be possible to offer the same
UI both with SDL & ncurses. SDL can look nicer whereas ncurses on
console would support copy/paste.)
