Yes WS_POPUP is the correct style to use in Win32, however it doesn't seem to be used in Windows CE (all windows have no borders anyway). Also all of the examples use a style of 0 (no WS_POPUP flag).

Would that really change much? - Possibly - it can do as Windows is a little bit eccentric - that was the only difference I could see between your code and mine.

If it doesn't work, give the SHFullscreen a try, since there's nothing else left. But it's just strange as I seem to having no trouble. Maybe there is menus and stuff in MameCE which changes things. Who knows.
