Calling full-screen xmame from a full-screen SDL application under X

Hello all,

I’ve tried executing a full-screen xmame application from a full-screen SDL
front-end under XFree86, yet the xmame application does not appear. My guess
is this has something to do with the window focus, but I might be completely
off. Any thoughts on how I can make the xmame application place itself on top
of the front-end?

Regards,
