Derailing the thread to the topic of Dosbox in general (as is tradition): on Android, ‘Magic Dosbox’ works quite nicely thanks to the feature of adding custom widgets on the screen, for keyboard or mouse keys and, in the paid version, combos. The app is freemium, but it's pretty cool and cheap so personally I'm not even bothered.
Also, Retroarch has a Dosbox core, and Retroarch with some cores works on the PS Vita handheld console, and as a result there's Dosbox on Vita. However, it's said to be quite a pain to set up for a particular game, with text configs. For jailbroken-PSP owners, Dosbox is apparently ported as a homebrew app. I'm vaguely looking forward to trying System Shock on Vita, but with my luck I'm not holding my breath.
Dosbox also runs on Xbox One via Retroarch. So in essence the Xbox can be a retro Windows gaming machine as well. PCem also has a very primitive core. If only Dosbox-X had a core we could run Windows on Xbox which is still possible, I think, using Dosbox or PCem.
