Parsing vitasdk headers

To take full advantage of this script, I recommend parsing the vitasdk headers before running it:

1. Generating a Ghidra-parsable headers

1. $ arm-vita-eabi-gcc -P -E $VITASDK/arm-vita-eabi/include/vitasdk.h -D"__attribute__(x)=" -D"__extension__(x)=" -Drestrict= -D__restrict__= > vitasdk_header.h
   • Use vitasdkkern.h for the kernel headers
2. Now open vitasdk_header.h and remove the typedef unsigned int wchar_t; (line 3)
   • If generating the kernel header, remove all the inline macros (ksceKernelCpu*Context, ksceKernelCpuUnrestrictedMemcpy)
   • If generating the kernel header, change SceKernelProcessInfo's unk[0xE8 / 4 - 6] to unk[0x34]

2. Parsing the header

1. Open Ghidra and go to File -> Parse C Source... and select vitasdk_header.h
