dosbox update?

[Ken Cunningham]

Sounds like you're all over this.

We can keep the 32bit builds on PPC and all Intel systems prior to Mojave. The patches and Portfile might need to be tweaked for the current release.

For Mojave, we have two options:

1. force a 64bit build no matter what (easy)

2. do an SDK trick with MacOS.10.13.sdk so it builds 32bit on Mojave (pretty easy, but required manual intervention)


Personally, I'd do them both -- make 32bit Mojave a variant maybe.

Are you interested in helping out James Slor with this? He is around occasionally, very rarely these past couple of years?


BTW I have exactly the same questions about what I'm going to do with basiliskii, sheepshaver, and other emulators that work better 32bit.

And yes, you are right for most things the 64bit performance is more than enough and the more power the host machine has the less noticeable it is. Only the “latest” Dos games, most prominent the build engine games (Blood, DukeNukem 3D, Shadow Warrior…), might tax your system.

And I’m also doing straight unmodified snapshots when SVN changes at https://www.dropbox.com/s/kbrf5elbcu66kst/Dosbox-Snapshot.dmg?dl=1 - all in ppc (10.4/10.5) and 32/64bit.
