I see all of my DOS-emulated games no longer work in Catalina, as it no longer allows non-64-bit applications. What are the plans to address this?

In my sarcastic voice, I'm going to offer my sincerest congratulations to paying 1000+$ for a machine which regularly screws you over. Maybe you should use FreeBSD or NetBSD.

In my actual voice, what you'd need to do is probably install something like Lutris or DBGL and install a local copy of DosBox. Point games there.

Fedora is discontinuing bootable images for x86-32, but they aren't insane enough to disable multilib.

In my sarcastic voice, I'm going to suggest ignoring people who make unhelpful comments and don't really know what they're talking about. And I'm going to say that in my actual voice as well. You can just download 64-bit Boxer (https://www.dosgameclub.com/forums/topic/boxer-app-64-bit/) and use that.

GOG already pushed a bulk of Mac-only updates for DOSBox games.
Just wait a few days and your all DOS-emulated games will get newer DOSBox.

Not sure you understand the definition of sarcasm. The machine serves me very well, else I wouldn't buy it.

Was expecting posts like this. I suppose you have little else to do than attacking someone's personal choices and preferences who is asking a question. Is that an official thing? Is GOG planning on re-wrapping all of these in a 64-bit package? Thanks. I'll head in that direction then. Most of the reason I purchased these were they were wrapped up and easy-to-execute without fuss (i.e., dealing with the unique nature of some games saving features such as copying diskettes, handling of drive partitions, tweaked settings in the emulator that I had assumed GOG had spent some good time with, etc.).

Is there an established guide or method everyone recognizes for porting these (and their GOG-established settings) into DOSBox or Boxer?

GOG never announce it, but they have started to do it.
I already got about 20 Mac-only updates in past two days.

The real problem are the heaps of games from 1996--2015-ish that are 32 bit only. If you do not play anything from after DOS went out of vogue, you are in the clear.

Right. So DOS-based games, which are wrapped in an emulator, are going to be ok as long as an updated emulator is used. Everything else that executes natively is going to have a greater problem in the coming years.

It's pretty simple with Boxer. For example, I have Magic Carpet, which is 32-bit and hasn't been updated. (I haven't seen any updates for DOS games, but I only have a few of those.) To make it 64-bit:

Launch 64-bit Boxer, click "Import a new game", navigate into the GOG package for Magic Carpet to find and open the Contents/Resources/Magic Carpet.boxer package, find the D.iso file, drop that onto Boxer. When it's done importing, do "show in Finder" (to show to new Magic Carpet app) and close. Open the new Magic Carpet app package and copy over the C.hardisk and the preferences files from the old Magic Carpet.boxer. That's pretty much it. In the new version, select single.bat or carpet.exe to run, or hidden.exe for the expansion. (The select.exe which is supposed to let you choose doesn't seem to work.)

That's very euphemistic. Unless someone manages to create a compatibility layer the only chance is getting every developer to update the back catalog which might be a huge amount of work depending on the way the games were developed.

Which considering the fickle matter of license agreements, how many developers can either decide it isn't worth it or have gone bust, and lastly publishers, really does put a lot of games on the chopping block. Who would want to go back to a decade old game and deal with the WOMBAT of resources?

And here's the thing, Apple holds the keys. They can arbitrarily block things the OS level.

I am also interested to know if GOG will do something so 32bits games will run in MacOS Catalina. I do not know if it technically possible.

me to.

also it would be good to know if any games are working under OS Catalina - I cant buy any more becaus I dont know and until now I couldnt find the info...

I think DOSBOX 0.75 might have x64 version after all. All we need is just wait for couple more years.

DOSBox already support 64bit. Talk to GOG if your DOS game comes with the 32bit version of DOSBox or install the 64bit version of DOSBox yourself.

As for 32bit games on Catalina setup a dual-boot with an older version of MacOS or Windows, those are your best options currently.
