Optional dependencies (lots works fine without them, are still recommended)
~ BSC_ParkFeatures.dat - These are for the placement arrows; Download and installhttp://sc4devotion.com/csxlex/lex_filedesc.php?lotGET=437. Keep the file mentioned (you can delete the rest if you wish) (Can't find this, any help would be appreciated)
~ PEG-CDK3_SUPER-PAK_RESOURCE.dat - This is for a simple overlay texture; if you don't use PEG stuff, then you don't have to get it; Download http://community.simtropolis.com/files/file/19880-peg-cdk3-super-pak/ and keep the file mentioned (you may delete the rest if you wish).
