Well the most popular games have been ported already, Duke3D, Shadow Warrior etc, most others play perfectly fine through dosbox...
If you meant for X360 though, well i can't see
fans doing that, at least, not in a legal way...
Unless what you're originally asking fo, is permission from 3DR for fans to port thier games to xbox..? In which case, i think they need the right tools, like a proper X360 dev-kit or something i guess...
But if what you're asking for is PC ports for old classics like Duke3D and Shadow Warrior, or even Rise of the Triad or Blake Stone, well fans made postrs for some, and dosbox pretty much works for all of them just fine...
As a matter of fact, GOG.com started selling some classic apogee games recently, you might want to check them out, they work fine on newer OS's (XP and Vita)

It says "coming soon" on some, this spans over a week or two untill they're available, so it's no big deal...
