Have you considered changing the .exe export table to include the known methods and data externs?

How do you build the fake .pdb from .h ?

All the information from the TS++ project on the GitHub repo can be found as a PDB file in "pdb/GAME.pdb".

I can have a C debug breakpoint at AddMessage.
I dont yet know how to read the message string, nor how to detour/hook the address just yet.

Code:

Visual Studio does not like the pdb so it wont resolve any methods on stack trace.

Code:

"\TSpp\pdb\GAME.pdb"
