Exult Forum

Is it possible to port Exult for DOSBox (which is actually a DOS emulator that runs on the XBOX)?

No, for a couple of reasons. First, DOSBos is not something you can port anything to, it's just an emulator, an application and not a platform or operating system (like XBox, Playstation, DOS, Windows...). Ignoring that reason, there is only the question whether you can port Exult to DOS to play it on the XBox port of Dosbox. IMHO it's not possible to port Exult to DOS. You are better off playing the original games on Dosbox.
OR you search on the net for the XBOX port of Exult (it's been done, just not officially since you can't do that legally.

I'm assuming you're posting this using a computer. So why don't use your computer to play Ultima 7? Sheesh.
Besides, I'm sure the illegal Xbox port of Exult is ages out of date.
