| This LINEAR memory mapping was added with [[8.0.0-18]], see [[SVC#enum_MemoryOperation|here]]. This replaces the original 0x14000000 mapping, for system(memory-region=BASE)/newer titles. The Old3DS kernel uses size 0x08000000 for LINEAR-memory address range checks, while the New3DS kernel uses size 0x10000000 for those range checks. System-module code doing vaddr->phys-addr conversion uses size 0x10000000 instead of 0x08000000.
