Well, it took me about 3 hours to have the game running on metro, so it was really a fast port!
I had to modify a few things, the most important one was compiling the 3rd party libraries so I can compile for ARM and x64 too.
Another change I made was supporting the accelerometer, as it wasn’t implemented (I’ll make a pull request with my implementation).
My PVR CCZ texture didn’t load, so I used PNG’s instead.
Windows 8 requires you to support snap view mode, so it is quite annoying to implement but it is a must to pass their review
Bottom line, Cocos2d-x is great !
