== MainThreadPriority ==
 +
Ranges from 0 to 0x3F.
 +
 +
== SystemResourceSize ==
 +
When this is non-zero, the kernel reserves this amount of memory and dynamically uses it as needed for page table pages, KMemoryBlocks, and KBlockInfos. When this is zero, the process uses global shared heaps for these.
 +
 +
This enables a process to sacrifice some of the memory available to it in order to have higher limits on these resources, thus enabling the use of SvcMapPhysicalMemory.
 +
 +
Maximum size as is 0x1FE00000.
 +
 +
 +
== Version ==
 +
0 for all titles.
 +
 +
[8.1.0+] Now set to 1 for certain titles.
 +
 +
[9.0.0+] Now set to a proper version field for all titles.
 +
 +
== MainThreadStackSize ==
 +
Must be aligned to 0x1000. If zero, kernel will start the process's initial thread with sp=0.

Bit31-19: Major version

This encodes the intended kernel version for the program.
−
Bit18-15: Minor version

−
Bit14-0: Zeroes

The kernel requires that the intended version is >= the minimum supported version (3.0 for all released kernels), and <= the current version.

Kernel version is derived from/equivalent to SDK version:

* Kernel Major = SDK Major + 4

* Kernel Minor = SDK Minor
