Is it (still?) possible to define unlock cost and minimum tech levels on a per config basis? I tried to do some custom configs for an engine with a ModuleManager patch, though none of entryCost,sciEntryCost,minTechLevel etc. have any effect for me when in the ModuleEnginesRF or ModuleEnginesConfigs (or the configs themselves) nodes.
I did look at the source code on GitHub, though my C# skills are very limited so i couldnt really find any more information on whether this is still implemented and i also didnt find any existing patches which use these features.
