I have this running on the ipad
I have xcom running on my ipad. In fact it works perfectly, once you get used to not having a mouse. I did this first by jailbreaking my ipad and downloading and install "dospad" which is a full
dosbox implementation for the ipad. Then, after I updated my ipad, without a jailbreak, I was lucky
enough to see dospad get approved by Apple for about half a day (before it was removed) and installed it. It also runs xcom, but not quite as well, that the graphics do not refresh as quickly,
but it still works. The reason is the jb version allows "cpu=dynamic" ins dospad.cfg, but the "apple"
version does not.
In any case, the sound works, too. Just configure a blaster in dospad.cfg but don't fill in any interrupts for it. It will just work.
Also, you need to download a version of xcom that has been patched, so look for 1.44 I think.
This one will work just fine. I think the steam one can too, just load it into dospad as as well.
TFTDvwill work too. It is the same, but I never played it.
I love playing is on the ipad, but I stopped for some time as I found it was too stressful and
addictive having such a nightmare combination of technology in my hands.
Finally there is also isochron, which will be for the ipad and is a complete rewrite.
For all the above, just google "dospad xcom" "isochron ipad" etc.... exercise left to the reader
