Someone told me to recongfig /usr/share/applications/hildon/osso-xterm.desktop file

just as

[Desktop Entry]
Encoding=UTF-8
Version=0.1
Type=Application
Terminal=true
Name=xmame
Exec=/usr/bin/osso-xterm cd /home/opt/usr/share/xmame/
Icon=xmame
X-Osso-Type=application/x-executable

and when I push this icon, it'll go to an xt platform that already gets into /home/opt/usr/share/xmame/

Is that right?I've tested but no use
