System Sector

System Sectors are locations unique to Kingdom Hearts Re:coded, replacing the Debug Areas that appeared in Kingdom Hearts coded. They can be accesed through Backdoors, and are found in every world. A System Sector can have several different floors. Once one floor is cleared, a transport appears, allowing Sora to move up a floor. Eventually, a terminal will open, allowing Sora to leave the Sector altogether.

Inside each Sector reside bugs. If a section of the Sector is colored red, enemies must be eliminated. Once Data-Sora has defeated bugged Heartless, the room will become blue. Defeating Heartless and destroying Bug Blox will earn Data-Sora System Points, or SP. Once Data-Sora leaves the Sector, he will be prompted to redeem his SP for rewards. The first few rewards will be highlighted in yellow, meaning that they are "system rewards", and that they can only be redeemed once. Below these are other prizes, which can be obtained repeatedly. Once the player doesn't have enough SP for an item, they can trade the remainder in for equivilant EXP or munny.

After completing Traverse Town, System Challenges become available. Once Data-Sora enters a System Sector, he will be rewarded 1000 SP. Before he can enter each floor, he will be prompted to wager 10, 30, or 50 percent of the 1000. If he can complete the challenge, he will be rewarded the amount wagered, with a multiplier added. If he loses the challenge, he will lose the amount of SP wagered. If the player runs out of HP during a challenge, they lose a large majority of their SP. Each floor has a separate challenge.

Sometimes, in high-leveled System Sectors, while exploring it, a Virus may infect one of the floors at random, infected floors will force you to wager all the SP you have earned before, which it means that if the challenge is not completed, or if you run out of HP during it, you'll lose all the SP you earned in previous floors (this could be benefical if, the challenge is rather simple and it could mean a big reward on SP). An infected floor is completle bugged, meaning all sections are red, and making every bugged Heartless stronger.
