P3PrecacheIncrease

As the name suggests, this project increases the precaching limits within Postal III's engine. Whose values are based on Source Engine 2007, as can be found within its leaked code's headers and engine binaries.
This code is meant to be put alongside a .VDF file in addons folder, or injected with slight modifications using LoadLibrary in a custom P3.exe or client.dll.

What code does:

• Memory patching:
  • changing the Vanilla precache values to new modified ones during server's StringTable initialization,
  • patching out various references to old index bits of the Sounds table inside of SVC_Prefetch and SoundInfo_t's Write and Read functions to the new index bits.
• Detours:
  • GetXXXXXX¹, SetXXXXXX¹, and PrecacheXXXXXX¹ functions inside of CGameServer and CClientState to point towards the new precache arrays.
