The SYSTEM mem-region size is calculated with: size = 0x08000000 - (APPLICATION_MEMREGIONSIZE + BASE_MEMREGIONSIZE).
The SYSTEM mem-region size is calculated with: size = FCRAMTOTALSIZE - (APPLICATION_MEMREGIONSIZE + BASE_MEMREGIONSIZE).
Support for type6/7 was [[NCCH/Extended Header|implemented]] in [[NS]] with [[8.0.0-18]], these aren't supported in the ARM11-kernel itself yet.
Support for type6/7 was [[NCCH/Extended Header|implemented]] in [[NS]] with [[8.0.0-18]], these are only supported in the [[New_3DS]] ARM11-kernel not the regular 3DS kernel. These two types are the only ones supported by the New3DS kernel.
