How x86 dependent is OpenMW?

BTW, Arm OGRE exists http://www.ogre3d.org/forums/viewtopic. ... 6&start=50

Also, bullet seems to work fine on ARM too, since it apparently runs on android.

Did I miss any important dependencies?

Going ARM should not be a major problem. As I wrote in another thread the only thing we possibly have to watch out for is endianess (depending on in which mode the ARM CPU is running). Actually I am not 100% sure, if our ESM code would play nice with different endianess. But even if it doesn't changing it would be anything but hard.

Morrowind controlled just fine on the XBOX with a dual-stick setup. Actually, I'd go as far as saying I preferred it since it fit better with the slower pace of the game. I even usually prefer WSAD+Mouse.

it will RUN, but nicely is not promised due to architecture differences. For this reason you have to reoptimize XNA projects across each platform (zune, winphone, Xbox, PC)

DOH!

and a hella more powerful. 3 Cores @ 3.2Ghz a piece.

it has a GPU something similiar to a high 8000 series from Nvidia. the reason games look good on it, is that its optimized and not much AA. (like no AA i think :| )

it wouldn't surprise me if it was easier to get it working on 360 than on Original, assuming we had SDK's for both machines.. :P

some can dream tho.
