In addition to Executor/DOS, a non-released version ran on the Sun 3 workstations (they too had 680x0 processors) and Executor/NEXTSTEP ran on NeXT machines, both the 680x0 based ones and the x86 powered PCs that could run NEXTSTEP.
Executor was the least compatible because it used no intellectual property from Apple. The ROMs and system software substitutes were all written in a clean room--no disassembly of the Apple ROMs or System file.
Although Executor ostensibly has a Linux port, it's probably hard to build (I haven't tried in a couple decades) in part because to squeeze the maximum performance out of a 80386 processor, the synthetic CPU relied on gcc-specific extensions.
I know a fair amount about Executor, because I wrote the initial version of it, although all the super impressive parts (e.g., the synthetic 68k emulator and the color subsystem) were written by better programmers than I am.
> I feel like that’s a bit harsh, but I’ll admit that it is needlessly inflammatory.
You're asking for a courtesy here that you failed to extend to others.
When you write a hit piece on someone's hobby volunteer code, and then you get called out for being unduly mean, I don't think you get to complain people are being harsh to you. You chose to devote hours of your time to dismantling something someone put years of effort in, entirely as a fun hobby. (Antique Mac emulation is certainly not the highway to riches.) You say 'inflammatory', like the issue here is that you're slightly heated and passionate. No, the issue here is that the piece boils down to bullying other people because their fun hobby projects don't meet your esoteric standards ('no Github releases!').
> I wasn’t in the best state mentally when I wrote that. (I do sometimes worry that I’m responsible for the disappearance of Paul C. Pratt…)
Nothing about your mental state gives you licence to bully others. Their emotional states are no less important than yours.
I think the MuseScore video is reasonably good reference for doing that sort of critique right. I'd gently point out two things. One, the MS video takes time to first explain what good UX is and why it's good, gently winning the viewer over with positive examples. Then it contrasts MS against best practice, relying on that earlier set-up work to ensure the viewer can follow along and see how MS is not quite hitting that mark. Two, it never denigrates MS; instead, it repeatedly affirms the author's enthusiasm for the product. It comes across as fairly compassionate and constructive criticism. Your piece, irrespective of its intent, didn't come off that way.
If you do want to do more criticism in the future, the MS video is a good point of reference. But I would hasten to add that good criticism is genuinely very hard. It takes work to do it right. It's not enough to simply be compassionate, you also have to demonstrate that compassion by weaving it into the final work of criticism. It must be a constant thread from start to finish, not a box one ticks off at the start or end.
A second option is to avoid criticism as such. Your piece could have easily been reframed as 'Mac emulation is really cool, built by these absolute legends, but none of these tools are quite right for me, so I made this fork that scratches my itches, and you might like it too!'. It gets the exact same points across, but does so much more gently.
That's not to say there isn't, at times, place for criticism strictu sensu. There is. But criticism is most effective when it is most constructive. Less cathartic, maybe, but catharsis at the expense of others is hardly something to aspire to.
I've taken the time to browse some more of your site and I think there's some really cool stuff on there. Don't be discouraged, or fall into the trap of being defensive, you have worthwhile things to say. Just do it with the same thought, patience, and compassion you'd want others to extend to you.
vmware and virtualbox were backed by billion dollar corps
the 16 bit machines are much simpler than macs
game consoles had highly homogenous well documented hardware, and sold in much greater numbers (snes alone sold more than all macs from 1987 to 1995) so there's a larger community to draw devs and users from. writing a nes emulator is almost a weekend project now, it's so documented.
Connectix got bought by Windows, and InnoTek got bought by Sun, which is now Oracle. Connectix themselves started as a scrappy outfit making it possible to run DOS/Win95 on a Mac.
The core emulation was pretty much done and stable and optimised before the billion-dollar corps bought them out.
even a "tiny, scrappy company" has massive manpower compared to 99.999% of open source projects
