x50v snow with all emulators

[luscus]

Can any one tell me how to get rid os the snow or static on the bottom 3rd of the screen,? I have tried all emulators and as soon as I install a game, the lower portion of the screen tbecomes snowy and you can't see the controls, the game itself is viewable.

My axim is running ppc 2003 V3-

Thanks
