I'd love to get these in. 

Emblem   I'm going to add Gaius Marius as a hero:   And I'm thinking of rounding out their hero roster with the...   Gracchi Brothers: https://www.wikiwand.com/en/Gracchi_brothers The Republican Roman civ's only economically focused Hero options. You'd get two Heroes to train, who are a bit weaker than other heroes, instead of the standard 1 hero.

@Stan`was this addressed ? I see your comment in https://code.wildfiregames.com/D4669#203984 : In A26 we added another code path that uses the SDL instead, to check if functionality stays the same so it's okay if that particular code returns unplugged CPUs for now. It's only for the optin hardware detection on https://feedback.wildfiregames.com/ However _SC_NPROCESSORS_CONF is still in current master: https://gitea.wildfiregames.com/0ad/0ad/src/branch/main/source/lib/sysdep/os/linux/lcpu.cpp#L61

I think you are right, I remember that I installed some extra maps in version 25 or 26. I will try to fix it. Thank you very much for help. 

Yes, this change also requires tweaks to the AI's number of trained Civilians. It should train more of them.
