How to install a game
use 7-zip to extract -> game-folder
Copy the game folder to /home/user/[webOS-games]:
$ cd game-folder $ chmod a+x filename
e.g. filename = nfsuc in need for speed case or sims in case of sims3
$ preenv $ ./filename
Once you know that the file plays properly. you can add the menu button:
$ cd game-folder $ root # preenv # desktopgen appinfo.json # exit # exit
How to delete a game
Enter preenv and cd into the game folder:
$ preenv $ cd game-folder
Become root and use desktopgen to delete game icons:
$ root # preenv # desktopgen -r appinfo.json # exit # exit
Now you can delete the game folder itself:
$ cd .. $ rm -r game-folder
Deleting games installed with old preenv 0.1
Become root and delete the folder:
$ sudo gainroot $ rm -r game-folder
To remove the icon, you need to delete three files:
$ rm /usr/share/applications/hildon/filename.desktop $ rm /usr/share/dbus-1/services/filename.service $ rm /usr/share/icons/hicolor/scalable/hildon/filename.png
Refresh your menu:
$ killall hildon-desktop
