dir complete
sys complete

To complete "found all %&$#" and "#$^)@? complete" you need to put the background in the right pattern instead of the elements shown.
Each chapter has one level with such a background:

mod a - level 5
mod b - level 4
mod c - level 5
main - level 4
dir - level 7
sys - level 1

You dont need to finish the chapter (again) - once the background got unlocked, it stays that way.
If you have finished all those backgrounds you will get the "found all %&$#"-achievement.
Then you will be able to select a new chapter in the menu. Finish it and you will get "#$^)@? complete".
