Yep thanks for the tip, the 1st fix written under the video got asphalt 5 working from the icon.

I completely uninstalled the game and deleted all files,icons etc.
Then i re-installed the game again and it worked using this:-

Please take care typing and use the correct case where needed including game folder and game file names

Go into x terminal

1 sudo gainroot
2. mkdir -p /media/internal
3. cd /media/
4. chown -R user:root internal/
5. chmod -R 755 internal/
6. mkdir -p /home/user/webos/gamesave
7. cd /home/user/
8. chown -R user:root webos/
9. chmod -R 755 webos/
10. ln -s /home/user/webos/gamesave /media/internal

- i then created a folder in /home/user called applications and copied the com. game folder into this folder (all this was done using filebox) -

Install game with this

open x terminal

1 sudo gainroot
2 cd game-folder
3 chmod a+x filename

Test game from x terminal

1 preenv
2 ./filename

Game should load

if it works ok you need to exit the game, press ctrl and delete together and tap x on game window to close,

re-open x terminal window

3 exit (until x terminal closes)

create a game icon with this.

open x terminal

1 sudo gainroot
2 preenv
3 desktopgen game-folder/appinfo.json
4 exit (until x terminal closes)

Use x terminal at you're own risk if used incorrectly it can damage you're phone

If i have made a mistake please let me know.

I used Asphalt 5 v1.1.4
