How to install 'Python Performance and Interface Overhaul' to Caveman2Cosmos v38 properly?
I installed fonts. Then I unpacked PPIO v0.5.9.4.9.5. Then I replaced the content of ‘Caveman2Cosmos’ folder with PPIO content. The game could not start because it could not initialize the main theme.
That's not the latest version of the modmod and should really be removed from the OP, use version 0.5.9.5
