Did you try the SVN of Dosbox? (Or rather when was it?)
Same as the iOS port of Dosbox. It's very old and has no dynamic core so it's really slow in most cases
Actually no. I've tested on desktop only with a fork called DOSBox-X, for the additions it has.
All I have related to DOSBox on iOS is an old iOS 11 Xcode project by litchie for iDOS2, I got it compiled (with several errors) for iPad Pro, and it runs well; But I am only using MSDOS 6.22 and Windows 3.11 on it, with DOS games. The most demanding game I have tested on it was Grand Prix 2, and even with tweaks to core and clock speed, I recall it not being far from the desktop x86 version performance; always near 100% processor occupancy. QEMU's UTM fork for iOS also been tested for this game, slightly better performance, I can even play Grand Prix 3 with a Win98 VM at a reasonable speed, but I believe with a 2020 iPad Pro I'd get near desktop QEMU performance from it.
Just to make the point stick, I've tested UTM with an iPhone X and it does run Ubuntu 16.04 (or was it 18.04?) with near desktop speeds. All I need now is to pair keyboard/mouse and plug a cable to a HDMI monitor... I was about to try out Windows 10 on it - I have seen folks on youtube trying Windows XP, 7 and even OS X Snow Leopard on UTM.
The developer of UTM has a golden mine in his hands if he does indeed port his app to macOS like he has said before.
EDIT: But then, neither iDOS2 and UTM have 3d acceleration for games, which is a must have for me now. However, there's a patch to bring 3dfx/glide support to QEMU, if it worked on ARM, then the UTM developer would be convinced to adopt it too. Still, there's one hole left to cover and it is Parallels/VMware's job to cover it: Windows games that require DX11/DX12. Pretty sure Parallels have the upper hand on it there if they really demoed an ARM Parallels version rather than emulating through Rosetta 2 in that keynote last monday.
The Tomb Raider game they demoed was a x86 from Mac App Store emulated through Rosetta 2; I was able to see that there is definitely a speed penalty in that too.
