What's happening with DOSBox on Apple Silicon (M1, M2)

Update 06/30/2022:
I forked Boxer and made some quality of life enhancements. Check out this video for more info on that: • Boxer Update (Fixing C...
Original video description:
Today's video is about DOS emulation on Apple Silicon Macs. We will look at the performance of a few native arm64 DOSBox forks (including the vanilla version itself). We will also look at the performance of Rosetta 2 and its problem when running emulators, including DOSBox.

One tiny detail: Boxer is actually powered by DOSBox Staging :) The developers switched from wrapping DOSBox SVN to DOSBox Staging and added that extra polish needed for truly native app.

This channel is a hidden gem. Great work!

[@reflekshun]

Such a great and clear explanation, awesome work making this!

[@wladimirrezende1475]

Dude, thank you for all the information and deep analysis. Amazing Job.

[@CaffeineLoaded]

Great video! Thanks for all of this work and sharing it with us.

[@fabzter]

Awesome analysis, It really helped me today :)

[@DocMacLovin]

"A universial bangery"? I do want to take part in that.

[@mantax55]

Thank you for doing this!

[@squeeeb]

Fascinating breakdown of the issues in play, like the double JIT scenario. Have you tried out DosBox Pure?

[@photolabguy]

You have solidified my purchase of a M2 MacBook Air.

[@stephanemignot100]

Irrelevant here but Boxer used to suck on slow machines, I use a DOSBox jit version on my 2004 eMac. I'll try your version if the Mini M2 comes one day, thank you! 71fps @640x480/138hz for Quake on the eMac, original Mac port of course.

[@accountname8819]

how can I use the touchpad as a mouse in Dosbox on a m1 Mac air? Thanks!

[@kiryarace]

Dosbox run perfect on m1 but i have no fullscreen resize window

[@larsandersen9134]

Is there any DOS emulator for Apple Silicon which also emulates MIDI soundcards like Roland LAPC-I or Yamaha or the like?

[@datashat]

Thanks for saving me hours of googling and messing around!

[@error4159]

Two JIT's is to much

1. Ditch Apple
2. Enjoy
PS: Kudos for the effort
x86 FTW!
