I dont really have much knowledge about this but heres the problem.
I wanted to put some games in the menu, and one of my favorite games is the freeware game called little fighter 2...
I copied it to the usb drive\portableapps\LF2
I doubleclicked the exe and the game worked perfectly... BUT when opened from the Menu the game comes with an error... Do you know if i can solve this problem in any way?
