Good news, everyone! I managed to tweak Kethane and recompile it for 0.90. I confirm that it is indeed working. I was able to scan, extract and convert kethane into fuel. I did not test it extensively, so it may still be broken. Steps to run Kethane 0.9.2 on KSP 0.90. 1. Download Kethane 0.9.2 and install as usual. 2. Download this library: https://www.dropbox.com/s/qufce6eeold7739/Kethane.dll?dl=0 and place it in [KSP_install]/GameData/Kethane/Plugins (there will be the original Kethane.dll that does not work, replace it). Note that I'm not taking over this mod, not joining maintainers team etc. I merely rebuilt it for my own benefit and when it worked, I thought that others may find it useful. I'm sure that Majiir will release proper version soon. The following license applies: Kethane-LICENSE
