i dont know what 'the mana world' is. but you would need to make a 'the mana world.desktop' file, and an icon .desktop file would probs need to look like: [Desktop Entry] Encoding=UTF-8 Name= (name of app) Comment= (comment about app) Exec=/home/user/ (location and name of app) Icon= (the name of icon) Terminal=false Type=Application Categories=GNOME;Application;Game; or something like that, but i know nothing about linux, maybe the linux junkies could advise better
