I got sidetracked, glad you got it working (i though that library was default) and thanks zanglang. Some of the advanced levels dont work well (slow or weird on tablet)... but fortunately there are alot that do work and when you solve them it feels rewarding.

Sure i can post source, but im not sure how much i had to change, probably just default keymappings and mouse/touchscreen ignore threshold for ignoring changes between stylus lift and setdown. Most of the work was just figuring out how to compile xerces and place the lib and include files in directories which the toolchain was expecting them.

I would like to have had more time to spend on it but i haven't lately. I'll try to put together the source sometime (weeked maybe) but it will require you to manually move the xerces libs and headers to certain scratchbox directories i'll put in a readme.

Hah yes a tilt mechanism would be fun... expecially for marble games. Will the usb port support that kind of device?
