EnableNonZeroFillMemory is a boolean determining whether kernel should it will memset various allocated memory-regions with 0x58, 0x59, 0x5A ('X', 'Y', 'Z') instead of zero. This allows Nintendo devs to find uninitialized memory bugs.
EnableUserExceptionHandler is a boolean determining whether kernel should forcefully enable usermode exception handlers (when false, only certain aborts (((1LL << (esr >> 26)) & 0x1115804400224001) == 0, typically data/prefetch aborts) that occur when the faulting address is in a readable region with MemoryType_CodeStatic will trigger usermode exception handlers).
PerformanceMonitoringUnit is a boolean determining whether kernel should enable usermode access to the Performance Monitors (whether PMUSERENR_EL0 should be 1 or 0).
EnableApplicationExtraThread is a boolean determining whether the kernel should increase the KThread slabheap capacity by 160. This also increases object capacities that are calculated based on number of threads.
CallShowErrorOnPanic is a boolean determining whether kernel should call smcPanic on error instead of infinite-looping.
MemorySize determines how much memory is available. 00/03 = 4 GB, 01 = 6 GB, 02 = 8 GB.
