The Sector Builder program is a simple program to rebuild destroyed sectors.
This program can only be unlocked by gaining Knowledge from Franz Hopper's Diary.
This program is available only in Lyoko's Terminal, or to any device connected to it.
You can select the sector to build by pressing the up and down arrows on the right part of the window. Once you have chosen a sector, right-click the keypad to enter the code automatically and launch the compilation process. If all of Lyoko is destroyed, you must build Sector Five first.
The compilation usually takes five minutes, but will last ten minutes if launched on a laptop.
Once the timer reaches zero, you only need to right-click the program once again to complete the build.
