Much of this page is wrong because much of the PAF is written in C++ but it works as a "function".

Module

ScePaf is a C++ runtime.

This module has many virtual tables that point to exported functions. It would be great to start from marking which function belongs to which vtable. This way we can restore initial class structure.

Version World Privilege
1.69-3.73 Non-secure User

Libraries

TOOL version of libpaf module is different from CEX and DEX as it has an additional library: ScePafAutoTestTty. Some TOOL system apps import that library and crash on CEX/DEX systems because of that.

ScePafAutoTestTty

ScePafAutoTestTty_9E10E873

Version NID
3.68 0x9E10E873

Can serve both as normal debug printf and also dump some PAF objects as XML. On external version of libpaf this function does nothing because it does not open tty output.
