After years of saying I'd never download RSO, I finally did. And I'm in love with Factorio again so thank you!

Is there a way to tweak the size of the ore patches in the starting area? The richness is great but I'm having issues getting a patch with enough size to generate the amount of resources I'd like.

Is there a tweak or a parameter I could look into?

Thank you!

There is only global resource size setting without special division between starting area and rest of map.
If you increase starting richness you might get more then one patch or they will get more dense. Size is predefined in config files in starting area section. You could edit those but game will overwrite changes like that on mod update.

Thank you.

When you say config files do you mean the base game config files or do you mean the mods config files?

Either way - where is that config and what's it called?

I mean the mod config files - when you extract the mod they are in resourceconfigs directory. vanilla.lua file contains the base game ores.
