Edit: Correction. Statement taken from the old PCE home page:

A complete 8086/80186 emulator.
Switching between 8086 and 80186 can be done at runtime.
witching between x86 and x88 can be done at compile time.

There's a similar statement on the current official site:

"An 8086/80186 emulator. The specific CPU model can be set to 8088, 8086, 80188 or 80186 at run time."

So, no need of older archived versions from forbidden sites 😉 But I have to switch to winbooze...

This is up to you. I've remembered PCE and mentioned in an act of kindness, believing the 80186 patch would have one more purpose.
That being said, all my experience so far was with v.0.1.7 and not the current versions.
I'm not even sure if the current versions aren’t somewhat of a re-write.
Because last time I tried a newer version it seemed like a different emulator to me.
The outdated version I was refering to is still on the server of the homepage, though. So Wayback indeed isn't needed.
Its files are located in /pub/pce

Ok. And there are also different types of "freeware" and "shareware" and some of them overlap. There are also different types of "aba..."***forbidden word***, a zillion of "copy...sh*t" "licenses" and a bunch of useless information of this kind. And I have a limited RAM 😉 But some are obsessed with these topics, others like to interpret these things as they fit for their attitude at the moment, while others (the worst case) fall into both categories.

And I thank you for the suggested 80186 emulator. But seems like the 80186 patched EMU386S.EXE will never be released to the public, because of the things we just commented.

I still don't want to discuss the hex-patches in public.

You don't have to discuss anything. Nevertheless, I just confirmed with DOSBox-X 2025.05.03 for Windows that my suggested patch actually works. As my patch does nothing about the nag screen (which can be simply skipped by pressing a key, so no need to remove it anyway), I can confirm that EMU386S loads in DOSBox-X with CPU type set to 186 if the following bytes are patched: 28CD-28D1: 54 58 3B E0 74 to B1 21 D2 E1 75; 28E2: 25 to 2D; 28E4-28E5: F0 74 to 10 78. This corresponds to the assembler code you cited in Re: Emu386 - 386 emulator for 286 .

Furthermore, it also loads with the processor type set to 80286, while it fails with the correct error messages on 8086, 80386 and 80486. If it fails for you in the same DOSBox version, I suppose you did not apply the patch correctly.

Good job.

I didn't knew that this "press key" actually works - never tried it. I read the thread and I was thinking - this must be easy to be removed. And it is. And the message for paid BETA advertising is... Anyway, I'll not discuss it anymore, as it is not of interest.

Strange. I see no differences, but it didn't work for me. Do you mind if I ask you something in PM? I really don't want to discuss here the fixes in this format, because of... you know, just in case.

P.S. I it's my mistake. After the last patching seems like I just forgot to copy the last version in DOSBox-X's "C folder" and I was actually testeing the previous version which still failed with 80186 😁 What a shame.

I'll do a new test.

Congrats, mkarcher, your assembly CPU test code is really working! I can confirm that the "shareware" Emu386 1.34 BETA 1 patched according to assembly code here really works in DOSBox-X with emulated 80186. It turned out that I just messed which is my last patched file and re-tested the faulty one. I have to be more organized, but...

And the good thing is, that I didn't reveal any code in hex, so no freaks will gonna mess with me 😁

P.S. Confirmation screenshot with DOSJP.COM not hanging (ignore the Emu386 error - it's because I tried to load it once more for the screenshot and it was already loaded):

Maybe this "Emulator for 286's" needs correction, if someone with a real 80186 machine may confirm, that there is some real benefit of the 80186/88 CPU patched Emu386.

Some 80186 testing update.

Kinda "386 game" is running on kinda "186 CPU":

Probably patched for 186 support Emu386 will make sense in combination with something like this thing:

BTW, there is still support for 186 CPU and its offspring, as they were generally used in the industrial/embedded sector. One example for a still available and supported product:
